1 00:00:00,000 --> 00:00:07,926 rc3 preroll music 2 00:00:07,926 --> 00:00:14,720 Herald: And welcome back from our studio live, as you could see in Halle! laugh The next 3 00:00:14,720 --> 00:00:19,200 talk will be Natalie Kilber. She will talk about tales from the quantum industry. 4 00:00:19,920 --> 00:00:25,040 Natalie works since many, many years on quantum computers to make them real and 5 00:00:25,040 --> 00:00:29,160 useful. 6 00:00:29,160 --> 00:00:33,440 Natalie: Hi, I'm Natalie, and I've been talking about the progress, the prospects 7 00:00:33,440 --> 00:00:39,200 and the poppycock, the nonsense of quantum technology, or you could also say tales 8 00:00:39,200 --> 00:00:44,560 from the quantum industry. A little bit about me. I'm a prehistoric creature that 9 00:00:44,560 --> 00:00:49,520 has been there since the field emerged. I'm the masses of stories for you today 10 00:00:50,240 --> 00:00:54,880 and you might ask yourselves, but why are you so gung ho about quantum computing, 11 00:00:54,880 --> 00:01:01,280 buddy? Well, if you look at the Moore's laws trends, then you know, already that 12 00:01:01,280 --> 00:01:06,720 since 2000, the clock speeds have been kind of stagnating and we're going smaller 13 00:01:06,720 --> 00:01:13,600 and smaller, and IBM is going to fabricate a chip of about two nanometers in 2023. 14 00:01:14,480 --> 00:01:19,200 The problem here is the smaller you go, if you go smaller than one nanometer towards 15 00:01:19,200 --> 00:01:24,320 sub nano meter scales, then you go into the quantum regime. And if you have a 16 00:01:24,320 --> 00:01:28,560 single electron transistor, you already have a quantum dot. That means that's a 17 00:01:28,560 --> 00:01:33,280 qubit, that's part of a quantum computer. But it's not reliable for classical 18 00:01:33,280 --> 00:01:40,320 computing, for any classical computation. So. Well, there we have it. We already are 19 00:01:40,320 --> 00:01:45,440 at a quantum regime if we want to go into the future. So why do I want quantum 20 00:01:45,440 --> 00:01:52,720 computers? I'm gung-ho about speed. I'm gung-ho about premium power. I want more 21 00:01:52,720 --> 00:02:01,040 juice. So first, look at your PC, now back to me now back in your PC. Sadly, it isn't 22 00:02:01,040 --> 00:02:09,360 an eight Core i9, or maybe it is so yet. Are you happy about your wiring? Well, I 23 00:02:09,360 --> 00:02:13,840 don't know why, but this fellow's also happy as a muffin about his wiring. This 24 00:02:13,840 --> 00:02:19,280 is a quantum computer in Google's lab, and you can see the wiring is not trivial for 25 00:02:19,280 --> 00:02:23,920 this. And this is just one little chip. So a quantum computer is an accelerator, and 26 00:02:23,920 --> 00:02:32,720 you need a co-host CPU to to do any sort of meaningful computation with it. And if 27 00:02:32,720 --> 00:02:36,400 you look at the wiring here, there's a different type of quantum computer. You 28 00:02:36,400 --> 00:02:40,800 see an optical table with optical components on it. I think this one is the 29 00:02:40,800 --> 00:02:46,160 QuEra startup, and this guy's not that happy about his wiring. You can see why. 30 00:02:47,520 --> 00:02:52,400 There's lots of other examples that look a bit difficult. And here specifically, you 31 00:02:52,400 --> 00:02:59,200 see a lot of controls that are sending signals into the quantum computer. And 32 00:02:59,200 --> 00:03:05,840 this one again, is QuEra with a bit better wiring. This is specifically a trapped ion 33 00:03:05,840 --> 00:03:10,880 quantum computer, so they use trapped ion. Quantum computers don't come in one 34 00:03:10,880 --> 00:03:16,000 flavor. We have different flavors with different bases of fundamental technology 35 00:03:16,000 --> 00:03:20,240 that we use with different types of components. So in trapped ions that use 36 00:03:20,240 --> 00:03:25,200 photonic components, there are photonic computers in itself. And for example, this 37 00:03:25,200 --> 00:03:31,520 one is a huge cryogenic fridge. So you go up to mini sub Kelvin stages right at the 38 00:03:31,520 --> 00:03:36,240 bottom and the first picture you see in it without his clothes, without the enclosing 39 00:03:36,960 --> 00:03:43,200 the enclave. And then again at the top, the massive wiring for just one chip. Then you 40 00:03:43,200 --> 00:03:48,240 have other examples like, for example, AQT Alpine quantum technologies over there 41 00:03:48,240 --> 00:03:54,560 in Austria, and they know how to stuff their cables really well and well. You 42 00:03:54,560 --> 00:03:59,920 might wonder why am I not talking about quantum inhalers? And well, if we define 43 00:03:59,920 --> 00:04:04,960 them, if we define quantum computers, so legs then a solid is a quantum computer 44 00:04:04,960 --> 00:04:12,640 too, you know, why a solid any sort of type of plant uses quantum phenomena as 45 00:04:12,640 --> 00:04:19,120 well. So because of photosynthesis, the light tries to travel as fast as possible 46 00:04:19,120 --> 00:04:23,200 to the side, and they do it through quantum tunneling and it solves it pretty 47 00:04:23,200 --> 00:04:30,640 fast. Yeah. So no quantum inhalers. Then look back at your PC, can it stand five 48 00:04:30,640 --> 00:04:35,560 gigahertz? You think you're unhappy about your clock speed? I think I won the 49 00:04:35,560 --> 00:04:39,680 Complaining game a quantum computer can do no more than 100 kilohertz, and that's 50 00:04:39,680 --> 00:04:45,040 twice the speed of the ENIAC back in the day. But then again, don't be so harsh in 51 00:04:45,040 --> 00:04:49,040 your setup or on the quantum computers. We still tinker with them with the 52 00:04:49,040 --> 00:04:54,720 capabilities we have. You've seen in the pictures before, there's a lot of wiring 53 00:04:54,720 --> 00:05:01,840 there, components that are quite big, that haven't been invented yet. So. The 54 00:05:01,840 --> 00:05:07,280 bottleneck component of a quantum computer of any set up, the slowest component is 55 00:05:07,280 --> 00:05:11,680 your bottleneck clock speed or a bottleneck in your clock cycle. And that's 56 00:05:11,680 --> 00:05:15,840 why they're so slow in quantum computers, they have digital signaling processes. 57 00:05:15,840 --> 00:05:20,960 That means you have to convert digital signals to analog and analog signals to 58 00:05:20,960 --> 00:05:26,480 digital signals again. And we have that everywhere in our phones and our cameras. 59 00:05:26,480 --> 00:05:31,760 Imagine just sound that is analog, that has to be converted into digital signals 60 00:05:31,760 --> 00:05:37,120 or, you know, literally light photons. If you take a photo in two digital signals, 61 00:05:37,120 --> 00:05:42,560 that's a analog to digital interface that we have. And here, because we're like 62 00:05:43,600 --> 00:05:48,080 shooting microwave pulses and, for example, superconducting computers and 63 00:05:48,080 --> 00:05:54,960 qubits, that's kind of difficult to do. So, yeah, you might say, but they are 64 00:05:54,960 --> 00:06:01,200 parallel and they do everything a little bit different. Yeah. For algorithms, when 65 00:06:01,200 --> 00:06:06,800 you have such slow clock speed rates, if your time to solution outlives you, that's 66 00:06:06,800 --> 00:06:13,920 a problem. If you don't live to see your solution, that's too slow and. You might 67 00:06:13,920 --> 00:06:19,185 want to listen to your computer, listen. So 30 dezibels or 40 decibels? This is 68 00:06:19,185 --> 00:06:46,906 what economists. You can hear this. Yeah, that's the 69 00:06:46,906 --> 00:06:47,906 Woman voices speaks "Welcome to sound of IBM. 70 00:06:47,906 --> 00:06:48,575 truth of that sound, but you needed it. That's so annoying. One tempers at the. 71 00:06:48,575 --> 00:06:49,800 You get into this by this. Then you have this wonderful. The nightmare is now. It's 72 00:06:49,800 --> 00:06:54,243 a quiet place. But one thing is always the same. We always talk about size and with 73 00:06:54,243 --> 00:07:00,739 size, I mean, we talk about qubits. You might read in Wired or Spiegel or wherever 74 00:07:00,739 --> 00:07:06,521 you want and hype articles or just articles talking about the advancements in 75 00:07:06,521 --> 00:07:14,960 quantum computing, how many qubits they they could instantiate on a chip. IBM 76 00:07:14,960 --> 00:07:21,360 released about 127 qubits in QuEra bit about 200 77 00:07:22,000 --> 00:07:26,960 years. The trapped ion one and IBM was the superconducting one of these cylinders and 78 00:07:26,960 --> 00:07:33,600 the cryogenic fridges. But here you have to discern a lot of physical qubits is 79 00:07:33,600 --> 00:07:38,880 good, but a logical qubit is what you need for computation. We have a high error rate 80 00:07:38,880 --> 00:07:44,240 for just one physical qubit because of the noise. Because of temperature. All types 81 00:07:44,240 --> 00:07:48,080 of noise. All types of environmental factors that you can't eliminate yet, 82 00:07:48,080 --> 00:07:52,160 because this is this is quite fundamental research how you can control these things 83 00:07:52,160 --> 00:07:57,120 and how you can adjust the parameters so noise stays low. And then again, we have 84 00:07:57,120 --> 00:08:04,400 these types of signals and in our normal classical devices where we need parody 85 00:08:04,400 --> 00:08:10,480 checks, where we need error correction and so do quantum computers. Error correction 86 00:08:10,480 --> 00:08:15,200 was a huge field that needs to be advanced, and we use things that are 87 00:08:15,200 --> 00:08:20,400 called surface codes and these are error correcting to get one logical qubit. So we 88 00:08:20,400 --> 00:08:24,640 have reliable computation. We need a lot of physical qubits. So you could say 89 00:08:25,360 --> 00:08:30,400 there's a lot of overhead for those error correcting code and parody checks. So if 90 00:08:30,400 --> 00:08:35,360 you hear about those, many Qubits have been have been accomplished by a company. 91 00:08:35,360 --> 00:08:39,120 It's usually physical qubits, but then another factor of 20, that's just one 92 00:08:39,120 --> 00:08:45,680 logical qubit that you can use. Yeah, that's difficult. And there's a famous 93 00:08:45,680 --> 00:08:52,160 physicist that said, Well, he's still alive, so it's actually on Twitter. And he 94 00:08:52,160 --> 00:08:56,480 said, Well, Qubits are like children's better to have a few high quality ones 95 00:08:56,480 --> 00:09:01,680 than a bunch of noisy ones. Yes, I agree. And John John Prescott has been at 96 00:09:01,680 --> 00:09:06,320 Microsoft before, and now he's at 8WRS. But at Microsoft, we witnessed 97 00:09:06,320 --> 00:09:12,160 Maironascandal. Well, we thought we can have a topological qubit that has no 98 00:09:12,160 --> 00:09:17,280 noise. That means if we have one qubit, we don't need these many physical qubits to 99 00:09:17,920 --> 00:09:24,480 have one logical one because it is a topological one with no with entrenched 100 00:09:24,480 --> 00:09:30,720 error correction. One could say by the physical nature. So you also run a blood 101 00:09:30,720 --> 00:09:36,080 cells. Fittingly, it was called the elusive marihuana particle because yes, 102 00:09:36,080 --> 00:09:42,400 we've been waiting for 10 years for this sort of maiorana qubit. But there was this 103 00:09:42,400 --> 00:09:49,440 scandal. The big maiorana qubits wasn't the big one. After all, they had to 104 00:09:49,440 --> 00:09:56,560 retract the paper that said they found one. So we're still looking for it. Yeah. 105 00:09:56,560 --> 00:10:01,440 But then again, it is better to have a few noisy physical qubits than none at all. 106 00:10:03,280 --> 00:10:08,080 So, yes, quantum computing is full of challenges. You've seen the wiring. 107 00:10:08,800 --> 00:10:15,440 Getting so many wires into one of those cryogenic fridges is very difficult. So we 108 00:10:15,440 --> 00:10:23,760 have to find new ways to get see my those those control those little controllers 109 00:10:23,760 --> 00:10:28,720 into that fridge. So we have to reduce the wiring, for example. And that's not a 110 00:10:28,720 --> 00:10:34,320 trivial task because you get a lot of resistance when you go colder for four 111 00:10:34,320 --> 00:10:39,600 cables, for example. We're advancing microwave technologies with quantum 112 00:10:39,600 --> 00:10:46,560 computers. And one thing that kind of worries me the most is that we don't have 113 00:10:46,560 --> 00:10:52,000 quantum memory yet. So cue run from random access memory because at the moment, a 114 00:10:52,000 --> 00:10:56,880 quantum computer is just an accelerator. So it's a read only memory. So everything 115 00:10:56,880 --> 00:11:02,640 that is on the chip or on the qubits, on the setup that is read out like that you 116 00:11:02,640 --> 00:11:07,680 can store them or you can do any more meaningful computation. So that's a huge 117 00:11:07,680 --> 00:11:12,880 bottleneck. Another thing is the ethical dimension we have to use in 118 00:11:12,880 --> 00:11:18,240 superconducting quantum computers. A lot of helium and helium has supply 119 00:11:18,240 --> 00:11:22,480 bottlenecks, with just two companies Qatar Gas and then one Northern Texas company 120 00:11:22,480 --> 00:11:27,840 that supplies helium. That is not really the problem, though, because we need even 121 00:11:29,440 --> 00:11:33,360 something else. We need three helium, which is an isotope, and that you get by 122 00:11:34,640 --> 00:11:41,040 as a nuclear byproduct for tritium. That's not something I want to I'm going to count 123 00:11:41,040 --> 00:11:45,760 on, especially because these are limited resources. And sometimes the components in 124 00:11:45,760 --> 00:11:50,240 quantum computers themselves. They're also rare earth metal. Those are also limited 125 00:11:50,240 --> 00:11:56,480 resources. And then people keep talking about democratizing quantum computers. Yet 126 00:11:56,480 --> 00:12:00,400 you have other problems there first. Not everyone needs access to something that 127 00:12:00,400 --> 00:12:05,920 doesn't, doesn't solve a lot of things yet. And to be honest with the security 128 00:12:05,920 --> 00:12:13,360 controls in place, it's kind of an open system already. But yeah, when we look at 129 00:12:13,360 --> 00:12:19,280 quantum, we have to think about the references. Which specs do you have to 130 00:12:19,280 --> 00:12:22,800 look for? And the magic here is common sense. I've shown you compared to what, 131 00:12:22,800 --> 00:12:29,440 you know, the components that you know. And again, the magic is common sense. And 132 00:12:29,440 --> 00:12:34,720 quantum computers are very specific that quantum technologies, the component of a 133 00:12:34,720 --> 00:12:40,480 quantum computer, the sensors, single electron sensors that we did. We use an 134 00:12:40,480 --> 00:12:46,320 MRI that we're using spectroscopy for microscopes and yada yada, even more 135 00:12:46,320 --> 00:12:51,920 things and quantum communication types. So semiconductors or or something else, 136 00:12:51,920 --> 00:12:58,160 semiconductor components or just our infrastructure and communication. They can 137 00:12:58,160 --> 00:13:04,240 be part of the quantum technologies as well. But you have to be also careful. 138 00:13:04,240 --> 00:13:11,120 Everything is quantum now. It's it's quite the hype. So finance is doing somehow 139 00:13:11,120 --> 00:13:18,000 quantum. I don't know what other companies think. Well, the buzzwords cyber isn't 140 00:13:18,000 --> 00:13:23,040 enough and used two buzzwords: quantum and cyber. I'm very curious what they do. Then 141 00:13:23,040 --> 00:13:28,640 there's quantum transportation. I'm lost here. I don't know what they do. I don't 142 00:13:28,640 --> 00:13:35,182 want to know. And here, I mean, I'm sure that is pain free. Yeah. You can also have 143 00:13:35,182 --> 00:13:43,182 to be in and actually I really wanted to find this in April 20 20. Yeah, so quantum 144 00:13:43,182 --> 00:13:49,355 computing is claimed to solve a lot of today's problems. Some companies claim 145 00:13:49,355 --> 00:13:54,081 they're battling climate change, that transforming the pharma industry to 146 00:13:54,081 --> 00:13:59,080 transform the finance industry into the break all encryption in the future, as we 147 00:13:59,080 --> 00:14:05,403 know. So quantum computers will break the internet in the future. Yet again, looking 148 00:14:05,403 --> 00:14:11,186 at the reasons estimations, not including the clock speeds or the actual 149 00:14:11,186 --> 00:14:17,043 performance, that's difficult to claim. But then again, looking at the references 150 00:14:17,043 --> 00:14:23,663 and the facts and the specs, not all claim these weird things, but the reference 151 00:14:23,663 --> 00:14:30,680 facts like see lobs from IBM. These are advancements that are meaningful. But then 152 00:14:30,680 --> 00:14:37,157 again, we have this flood of references of qubids of we're advancing this and that 153 00:14:37,157 --> 00:14:43,013 complexity theory claims. But how are you going to test these complexity theory 154 00:14:43,013 --> 00:14:48,252 claims? Well, because we don't have the Quibits, are simulated on a fantasy 155 00:14:48,252 --> 00:14:54,688 machine. And if anyone like this old chap here had to deal with theoretical 156 00:14:54,688 --> 00:15:03,061 complexity resource estimates a.k.a. fantasy language. Well, welcome to 157 00:15:03,061 --> 00:15:10,958 imagination land this town. This town is not a nice place for little fillies all 158 00:15:10,958 --> 00:15:15,042 alone. There are lots of twists and corners that could lead to the unknown. 159 00:15:15,042 --> 00:15:19,200 Let me guide your way, and I'll be sure to help you through. You could really use a 160 00:15:19,200 --> 00:15:25,297 friend of the , and luckily, I've picked my three favorite corners for you. Well, 161 00:15:25,297 --> 00:15:32,352 quantum applications were applicability is optional. So come on, let's start with the 162 00:15:32,352 --> 00:15:40,216 very well-known topic of optimization and the beginning of talks. I want premium 163 00:15:40,216 --> 00:15:47,546 power. I want maximum juice. So VSLI design, what is a VSLI? It's very large 164 00:15:47,546 --> 00:15:52,520 scale integration and it means you need to partition these little chips that we have. 165 00:15:52,520 --> 00:15:57,621 And the first chip that we had back in the day was an integrated circuit to help 166 00:15:57,621 --> 00:16:03,768 people hear better. So it was a hearing aid that Jack Kilby in 1958 designed and 167 00:16:03,768 --> 00:16:09,783 this thoughtful design thought were the basis of it is the basis for our 168 00:16:09,783 --> 00:16:14,626 technology everywhere, and it's not a trivial task to design these chips. So you 169 00:16:14,626 --> 00:16:19,792 don't have a lot of waste and we can pack more and more components on these little 170 00:16:19,792 --> 00:16:25,678 chips. So integrated circuits. If you don't know anything, IoT is that. Another 171 00:16:25,678 --> 00:16:31,249 problem? The mathematical basis for this problem is the same for network design or 172 00:16:31,249 --> 00:16:36,521 less waste and manufacturing like stenting or lasering, even flight scheduling 173 00:16:36,521 --> 00:16:41,232 between cities has this mathematical problem. Some might know it as bean 174 00:16:41,232 --> 00:16:47,000 packing, max card or multi card problems. You either seek to minimize or to maximize 175 00:16:47,000 --> 00:16:52,916 an objective. So those commentary problems are really one of the hardest one to 176 00:16:52,916 --> 00:16:58,782 solve. And I like to call them combinatorial black magic. These levels of 177 00:16:58,782 --> 00:17:05,659 hard to solve are classes in themselves, and this is actually a real graph. This is 178 00:17:05,659 --> 00:17:10,295 a Peterson graph, and you can tell it's it's black magic you might think. This is 179 00:17:10,295 --> 00:17:14,428 not that hard, but I'll show you a benchmark of max card problems. This one's 180 00:17:14,428 --> 00:17:19,303 NP hard NP complete. This is one of these fantasy language classes. It just means 181 00:17:19,303 --> 00:17:25,013 that no polynomial time algorithms for max card in general graphs are known. That 182 00:17:25,013 --> 00:17:29,164 means, again, your time to solution outlives you, and it's a problem if you 183 00:17:29,164 --> 00:17:33,742 need to wait until your solution comes and you die before. Or maybe it needs be a 184 00:17:33,742 --> 00:17:38,941 couple of hundred years. I don't know how long you live, but some say it's almost as 185 00:17:38,941 --> 00:17:45,080 hard as beating cut of meat and dark souls. But yeah, you don't live to see it. 186 00:17:45,080 --> 00:17:51,810 That's the that's the drawback of this. So yeah, you might think optimization, it's 187 00:17:51,810 --> 00:17:57,243 black magic, it sounds weird, but you have heard these terms before. I will 188 00:17:57,243 --> 00:18:02,848 specifically be gung ho and talk about nature inspired once the physics inspired 189 00:18:02,848 --> 00:18:07,860 algorithms. But, you know, neural networks you probably know to boost surge linear 190 00:18:07,860 --> 00:18:12,026 programing, mixed integer problem programing with a branch and cut, you can 191 00:18:12,026 --> 00:18:17,175 see the max cut promise that's in the in the brown part. And then, of course, other 192 00:18:17,175 --> 00:18:22,270 nature based methods like bad surge, genetic algorithms of small methods where 193 00:18:22,270 --> 00:18:27,217 it becomes quantum is. And that's that's what I like about the nature inspired part 194 00:18:27,217 --> 00:18:32,120 the nature inspired optimization algorithms. For example, they minimize the 195 00:18:32,120 --> 00:18:37,516 Hamiltonian of an icing model. So whatever mathematical but mathematical basis you 196 00:18:37,516 --> 00:18:43,350 have, you minimize and maximize your objective. Hamiltonians are something you 197 00:18:43,350 --> 00:18:48,722 use in quantum computing and the icing model I can explain later free up a little 198 00:18:48,722 --> 00:18:53,957 bit more time. So what we need here to with classical and quantum computers is 199 00:18:53,957 --> 00:18:59,830 benchmark, so we can compare apples to apples because classical computer and 200 00:18:59,830 --> 00:19:05,639 quantum computers is more like apples and bananas. So we need a common ground. And 201 00:19:05,639 --> 00:19:11,960 if you want standardized benchmarks for such problems, you can Google Chuck SHOOK. 202 00:19:11,960 --> 00:19:18,928 It's a it's an open source benchmark suit, and you probably see it in the slide. Good 203 00:19:18,928 --> 00:19:24,706 old Professor Katzgrabor. He has written this benchmark suit and he's gung ho about 204 00:19:24,706 --> 00:19:29,091 cats, so please spare him of cat content. So, yeah, I told you we'll get into the 205 00:19:29,091 --> 00:19:36,985 max cut benchmarks. This is from a paper of Cambridge, I think Cambridge quantum 206 00:19:36,985 --> 00:19:43,814 computing and these little circles, these little dots, steel nodes. And you can see 207 00:19:43,814 --> 00:19:49,682 they have done they've done it on a quantum computer for ten nodes. And it's 208 00:19:49,682 --> 00:19:55,392 very complicated. Yeah. And the problem here is when they went to 13 or twenty 209 00:19:55,392 --> 00:19:59,846 three qubits, logic of qubits, they had to simulate it. They had to put it on a 210 00:19:59,846 --> 00:20:04,710 fantasy machine and classical hardware. And yeah, that's that's also one algorithm 211 00:20:04,710 --> 00:20:11,132 they used. Vicki variational quantum ion solver and Qrolla, both of these are 212 00:20:11,132 --> 00:20:16,604 approximate algorithms you can think of very noisy, annoying quantum computers 213 00:20:16,604 --> 00:20:23,802 that don't spit out results. But if you run it 100 times, the majority of it will 214 00:20:23,802 --> 00:20:29,100 be towards the correct regime. And yeah, that's that's how you go about it. And 215 00:20:29,100 --> 00:20:33,880 this is a relatively new paper, and I have to say these resource estimations, these 216 00:20:33,880 --> 00:20:38,931 are amazing results, and I'm not worried about the algorithmic advances in quantum 217 00:20:38,931 --> 00:20:43,437 computing because we have smart people and I want more smart people. So if you want 218 00:20:43,437 --> 00:20:47,560 to, you should get into it. So, yeah, that's that's not what I'm worried about 219 00:20:47,560 --> 00:20:53,980 yet. I don't want to solve something for ten qubits or sorry, ten nodes on a 220 00:20:53,980 --> 00:21:01,184 quantum computer, yet we can solve something bigger. So this is from another 221 00:21:01,184 --> 00:21:06,623 paper from a nature inspired, physics inspired algorithm. Some already call it 222 00:21:06,623 --> 00:21:12,432 quantum inspired. These are 100 nodes, but at the lowest, you can see the physics 223 00:21:12,432 --> 00:21:19,421 inspired GNN and Pi G, and they managed to do it with a ten thousand nodes. So on 224 00:21:19,421 --> 00:21:24,722 classical hardware, the quantum the quantum algorithm put on classical 225 00:21:24,722 --> 00:21:29,836 hardware to overcome the cube hardware limitations by treating these physics 226 00:21:29,836 --> 00:21:34,731 algorithms as optimizes. So from a business perspective, if I want to have 227 00:21:34,731 --> 00:21:41,046 maximum power and maximum Dru's, I would use classical computers and use heuristics 228 00:21:41,046 --> 00:21:47,948 from quantum and classical until the quantum computers are ready. So, yeah, 229 00:21:47,948 --> 00:21:53,328 neuro, I'm sorry. Nature inspired optimization with quantum algorithms. 230 00:21:53,328 --> 00:21:58,990 That's like putting neural networks on steroids. Quite like that. This is the 231 00:21:58,990 --> 00:22:06,613 paper for it. But yes, we've been far deep into one corner. So I'll drag you back 232 00:22:06,613 --> 00:22:13,114 here and I'll show you another one. Some companies claim we were solving climate 233 00:22:13,114 --> 00:22:18,718 change with it. We're transforming pharma. And yeah, this comes from from ideas of 234 00:22:18,718 --> 00:22:26,047 physicists. What I said. Well, the nature is quantum mechanical. We might as well 235 00:22:26,047 --> 00:22:32,202 need quantum phenomena to simulate what is right. But yes, it's not that easy. This 236 00:22:32,202 --> 00:22:38,313 physicists played bongos and strip clubs. He's a real hero. Many of the physicists 237 00:22:38,313 --> 00:22:44,000 he's known for that are talking about chemistry. Here's ammonia. You don't think 238 00:22:44,000 --> 00:22:49,297 this is difficult, but ammonia is used for a lot of things in the world who use it as 239 00:22:49,297 --> 00:22:55,240 a base, if there's something acidic, you use it as a fertilizer, you use it in a 240 00:22:55,240 --> 00:23:02,687 lot of things in chemistry and even raw latex is has been transported with it or 241 00:23:02,687 --> 00:23:09,543 anything that has an acidic nature. You get it by a very difficult process. Well, 242 00:23:09,543 --> 00:23:14,765 it's not a difficult but energy expenditure high one. So you need high 243 00:23:14,765 --> 00:23:20,246 temperatures and high energies to put it into the harbor Bosch process, and it 244 00:23:20,246 --> 00:23:24,801 accounts for two percent of the global energy expenditure. It's a very famous 245 00:23:24,801 --> 00:23:30,269 problem that quantum physicists wanted to solve because it's really useful stuff 246 00:23:30,269 --> 00:23:36,631 ammonia. And if we can cut two percent of the global energy expenditure, that's a 247 00:23:36,631 --> 00:23:42,559 good thing. It's not trivial, though, Richard said it. It's not an easy thing to 248 00:23:42,559 --> 00:23:49,079 do here. You can see just the active side of an enzyme where you can produce ammonia 249 00:23:49,079 --> 00:23:54,608 without high temperature and high energy. Bacteria can do it by room temperature, 250 00:23:54,608 --> 00:24:01,003 ambient temperatures. There's algae. That's all types of bacteria that can do 251 00:24:01,003 --> 00:24:08,156 it, and the active side is called from FeMoco. You can see the resource estimates 252 00:24:08,156 --> 00:24:14,237 for half of the sides, for the for the energy to simulate, to see how this works, 253 00:24:14,237 --> 00:24:19,840 because bacteria can do it. We don't know how they do it. That's why we use so much 254 00:24:19,840 --> 00:24:25,440 energy in temperature. The enzyme and the material looks like this. And then again, 255 00:24:25,440 --> 00:24:31,766 look back at the computer for both parts. We need over 2000 logical qubits. Now, 256 00:24:31,766 --> 00:24:38,266 think back, physical qubits are by a factor of 20 or 100 more. So we're not 257 00:24:38,266 --> 00:24:44,038 here yet. Then again, classical computers can simulate it either, and we will 258 00:24:44,038 --> 00:24:49,006 probably simulated that on quantum, but we're not there yet. And to put it into 259 00:24:49,006 --> 00:24:55,800 perspective, to the far right the orange little molecules to form local bits in the 260 00:24:55,800 --> 00:25:02,014 whole enzyme. And you might wonder what is the THC cost while that's tens or hyper 261 00:25:02,014 --> 00:25:06,640 contraction, so you algorithmic advancements, I'm not so worried about. 262 00:25:08,080 --> 00:25:13,840 We're pushing, we're pushing the frontiers there. So yeah, but but the imagination 263 00:25:13,840 --> 00:25:17,760 land, the most powerful magic is common sense, and you should read it. So what do 264 00:25:17,760 --> 00:25:23,360 you think? Do you want to use a quantum computer or intermediate steps to find out 265 00:25:23,360 --> 00:25:30,000 what we need? Well, what people do these days is they're bit smarter and they do 266 00:25:30,000 --> 00:25:35,440 simulated. They do use some digital parts, but it's mostly haptic. Haptic means they 267 00:25:35,440 --> 00:25:40,320 simulate a little bit and they tested in a lab and got it tested in the lab. They can 268 00:25:41,440 --> 00:25:46,160 funnel down what they need to simulate. The paper I'm talking about for the 269 00:25:46,160 --> 00:25:51,200 smokable and theological cubits is a very recent one, so it's just a couple of days 270 00:25:51,200 --> 00:25:56,080 it's been published and I think this is a preprint even. And if you want to know 271 00:25:56,080 --> 00:26:00,080 anything about resource estimates and quantum computing for chemistry, 272 00:26:00,080 --> 00:26:07,040 specifically Nathan Vibha and Ryan Burbuja, a good place to look for. Then we 273 00:26:07,040 --> 00:26:11,360 are still a quantum applications for applicability is optional and it has been 274 00:26:11,360 --> 00:26:16,400 true so far, hasn't it? Let's move to a corner that hits closer to home, 275 00:26:16,400 --> 00:26:25,520 cybersecurity. We have to be specific here. I know a lot of companies claim 276 00:26:25,520 --> 00:26:30,080 there won't be any type of encryption as we know of in the future, because quantum 277 00:26:30,080 --> 00:26:37,197 computers will break it off for once a year to fifty sixty five fifty six years. 278 00:26:37,197 --> 00:26:47,200 As bad as 256 bit mode can be broken by quantum computers and symmetric key size 279 00:26:47,200 --> 00:26:52,880 symmetric encryption methods are known to be quantum secure the specific key size. 280 00:26:52,880 --> 00:26:59,440 So not really. What people usually think of as asymmetric encryption. So, yeah, 281 00:27:00,800 --> 00:27:07,120 these are some resource estimates to look out for. This is a Microsoft paper not too 282 00:27:07,120 --> 00:27:10,880 long ago, and they said through a punch line, it is easier to break elliptic curve 283 00:27:10,880 --> 00:27:17,360 encryption than RSA. Then Google, not too long ago, came up with two million noisy 284 00:27:17,360 --> 00:27:25,360 qubits or physical qubits to break RSA 2048 bit in eight hours. And then also the 285 00:27:25,360 --> 00:27:31,902 news paper saying that factoring a 2048 bit RSA integer can be done in one hundred 286 00:27:31,902 --> 00:27:36,240 and seventy seven days with about a little bit more than 13000 qubits, but with a 287 00:27:36,240 --> 00:27:41,360 multimodal memory that does not exist yet. These are incredible results over the 288 00:27:41,360 --> 00:27:47,280 years in resource estimation numbers. Yet again, let's put it into perspective. So 289 00:27:47,280 --> 00:27:55,520 2012 he said, it's a billion in this year. 2021 isn't over yet. This year, Google 290 00:27:55,520 --> 00:28:01,040 came up with 20 million noisy qubits and then Gaussian came up with a little bit of 291 00:28:01,040 --> 00:28:05,440 thousand or more, but let alone any workable implementation of curium as a 292 00:28:05,440 --> 00:28:09,360 purely theoretical nature as of now. So we're still in imagination land when it 293 00:28:09,360 --> 00:28:15,920 comes to breaking the internet as we know it. It's time to leave Fantasyland, or you 294 00:28:15,920 --> 00:28:22,080 might say, hey, but we did factor relatively high numbers back there in 295 00:28:22,080 --> 00:28:27,360 2013. You've heard this in the news. Well, yes, we did. But if you know the base 296 00:28:27,360 --> 00:28:34,160 beforehand, so if you know that with thirty five, the number thirty five, you 297 00:28:34,160 --> 00:28:39,760 can divide by five or seven if you know one base, that's a really easy thing to do 298 00:28:39,760 --> 00:28:44,880 and you can do that classically as well. So IBM had to counter published that they 299 00:28:44,880 --> 00:28:49,680 were oversimplifying quantum factoring, and the algorithm you use for it is 300 00:28:49,680 --> 00:28:54,000 Schwar's algorithm. It's one of the purebreds quantum algorithms out there. 301 00:28:54,720 --> 00:28:57,920 And then again, another one pretending to fact the large numbers and quantum 302 00:28:57,920 --> 00:29:05,920 computers. So no, we haven't been able to break it so far. Another one in 2019, and 303 00:29:05,920 --> 00:29:10,080 this is in very, very interesting one because IBM goes close to these problems 304 00:29:10,080 --> 00:29:13,360 and says, yeah, well, I want to test it. I want to simulate it. A sorry, not 305 00:29:13,360 --> 00:29:18,400 simulated. I want to test it literally in quantum hardware. And they did so, but 306 00:29:18,400 --> 00:29:28,080 they failed to factor just the number 35. So I think we're safe for some time. You 307 00:29:28,080 --> 00:29:33,600 have to think of quantum computers not as a quantum threat, but more as a quantum 308 00:29:33,600 --> 00:29:39,120 advantage. If someone knows how to steer encrypted data and store it about 20 years 309 00:29:39,120 --> 00:29:44,720 to decrypt it, you know, get it now and decrypted 20 years later and stored 310 00:29:44,720 --> 00:29:48,832 somewhere, they probably know where to get it unencrypted as well. They're more low 311 00:29:48,832 --> 00:29:53,200 hanging fruit for them, and I don't think they will wait until the quantum computer 312 00:29:53,760 --> 00:29:58,640 comes into fruition to do these sort of things. So let's put the quantum thread 313 00:29:58,640 --> 00:30:04,720 into perspective. Quantum computers are logical extensions of Moore's law strand, 314 00:30:05,360 --> 00:30:10,560 and quantum computers are tailor made for simulating the behavior of quantum systems 315 00:30:10,560 --> 00:30:16,400 like molecules or materials, and whether they lead to breakthroughs in cryptography 316 00:30:16,400 --> 00:30:21,040 or optimization problems. That is less clear yet, but we're we're pushing the 317 00:30:21,040 --> 00:30:26,160 boundaries. If anything, components of quantum computers are pushing the 318 00:30:26,160 --> 00:30:31,280 boundaries for us literally now, if we have better seeds like quantum random 319 00:30:31,280 --> 00:30:38,400 number generators for short Q, R and GS, that is very useful. We need seeds that 320 00:30:38,400 --> 00:30:42,560 are truly random. For example, in places where we can't use true random number 321 00:30:42,560 --> 00:30:47,200 generators that use entropy to generate the random numbers because in a data 322 00:30:47,200 --> 00:30:52,160 center, you don't want a lot of entropy, so you don't want temperature diversity, 323 00:30:52,160 --> 00:30:59,680 you want it to be cold and stay cold, or sometimes you don't have the possibility 324 00:30:59,680 --> 00:31:09,760 of having this anywhere where it's just not there. So we do make things smaller 325 00:31:09,760 --> 00:31:13,600 with it as well. You've seen the wiring, so we have to design microwave technology 326 00:31:13,600 --> 00:31:18,720 or any type of cabling, any types of chips, um, pre processes that can go into 327 00:31:19,760 --> 00:31:27,040 smaller and smaller spaces. So yes, we do need quantum computers and the research 328 00:31:27,040 --> 00:31:32,400 around it. We don't need it in business settings just yet because they're not 329 00:31:32,400 --> 00:31:38,480 ready. This is still very much fundamental research, and we should note that so 330 00:31:39,760 --> 00:31:45,200 mathematical concepts are more useful to find. Also new ciphers when we're talking 331 00:31:45,200 --> 00:31:49,040 about cyber security. And I'm not talking specifically about peak. You see, there 332 00:31:49,040 --> 00:31:52,560 are other mathematical mathematical concepts for asymmetric and symmetric 333 00:31:52,560 --> 00:31:58,240 encryption that can be that can be used. But for now, let's leave imagination land, 334 00:31:58,800 --> 00:32:03,612 and let's think about how quantum computers interface with the world. Well, 335 00:32:03,612 --> 00:32:11,302 I've shown you before that quantum computers sometimes have a crude and 336 00:32:11,302 --> 00:32:15,525 fridge, so if you look at the cylinder, you see the the enclosure of it. So this 337 00:32:15,525 --> 00:32:21,472 specific example, I use a superconducting computer for now, I've told I've told you 338 00:32:21,472 --> 00:32:27,398 before we need a host CPU and then a control system. Lots of peripherals and 339 00:32:27,398 --> 00:32:33,108 wiring to get into the cryogenic stage and the enclosure. And there we usually have 340 00:32:33,108 --> 00:32:38,757 an analog to digital digital interface. And at the bottom where it's the cold is 341 00:32:38,757 --> 00:32:45,317 the qbu. So you can think of it as, yeah, a huge system. So this is an example of 342 00:32:45,317 --> 00:32:50,333 Google's setup. And I think the key concept that needs to be highlighted here 343 00:32:50,333 --> 00:32:55,053 is the quantum computers are merely core processes. And as such, they depend on 344 00:32:55,053 --> 00:32:59,608 traditional compute environments to host a quantum processing unit, a cube you 345 00:32:59,608 --> 00:33:04,108 require as an analog to digital interface to to convert those signals back and forth 346 00:33:04,108 --> 00:33:09,482 and in turn, the application logic in the host CPU. You may connect to a network 347 00:33:09,482 --> 00:33:14,921 may. Some people think if I have it in the lab and it's not connected to anything, 348 00:33:14,921 --> 00:33:20,160 there's must be air gapped. But then again, you know how loud these devices 349 00:33:20,160 --> 00:33:26,560 are. So you kind of want RTP so people don't become death and we've corona, you 350 00:33:26,560 --> 00:33:32,484 kind of want people to work from home as well, so they won't be arrogant. For the 351 00:33:32,484 --> 00:33:38,024 foreseeable future, I guess we're for the next year at least. So the issue of cyber 352 00:33:38,024 --> 00:33:43,063 security and mass and quantum computing resources that is rarely discussed, these 353 00:33:43,063 --> 00:33:47,898 systems are and they will be hybrid systems for the foreseeable future with 354 00:33:47,898 --> 00:33:53,781 those CPU hosts with cloud based or managed APIs. And we need reliable 355 00:33:53,781 --> 00:33:59,239 services and secure services and architectures as this arises. So 356 00:33:59,239 --> 00:34:05,209 subsequently, the critical applications and data these systems will handle and 357 00:34:05,209 --> 00:34:13,408 store if it's the knowledge and the algorithms, how to how to simulate for 358 00:34:13,408 --> 00:34:21,853 Mocko we can produce the ammonia with less energy expenditure if we design new 359 00:34:21,853 --> 00:34:27,320 batteries. These are probably patents, so we want to secure the data behind it and 360 00:34:27,320 --> 00:34:33,240 those algorithms. So this means that all classical security best practices hold for 361 00:34:33,240 --> 00:34:39,238 quantum computers. So this example, the QC lab at Google, sees enterprise system 362 00:34:39,238 --> 00:34:46,141 constituted of a mix of Windows, macOS, Linux, maybe Azure, Adi, SAS network, 363 00:34:46,141 --> 00:34:52,840 containers, whatever platforms. And they're part of these industrial control 364 00:34:52,840 --> 00:34:58,880 systems and programable logic controllers, pulses or discrete process control 365 00:34:58,880 --> 00:35:04,516 systems. You know, anything in ICS, Escada that is rarely air gapped or physically 366 00:35:04,516 --> 00:35:09,018 means physically separated from any network. So we need API hardening. I see 367 00:35:09,018 --> 00:35:14,219 our security is not a big topic in quantum computing yet because it's still just a 368 00:35:14,219 --> 00:35:21,280 system on the internet, and it's not quite ripe yet. People sell it and companies put 369 00:35:21,280 --> 00:35:29,557 sensible data on there. So if this is back in the day got infected with the MIMO worm 370 00:35:29,557 --> 00:35:35,673 that was considered air gapped. No, I CS system is truly, really arrogant anymore. 371 00:35:35,673 --> 00:35:41,141 So before we offer quantum computing as breakthrough accelerators, we need to make 372 00:35:41,141 --> 00:35:46,240 them safe to use. So if you want to join me, let's protect quantum computers from 373 00:35:46,240 --> 00:35:51,250 getting pond. Thank you for listening to me. That's talk. 374 00:35:51,250 --> 00:35:59,713 Herald: Thank you so much. Um, we have some time for questions. So, uh. Audience, 375 00:35:59,713 --> 00:36:06,109 dear audience, please ask some questions. The hashtags are on Mastodon and Twitter 376 00:36:06,109 --> 00:36:17,787 hashtag RC3Chaos Zone, and the I.R.C. room is the Channel RC three Dash Chaos Zone. 377 00:36:17,787 --> 00:36:30,125 All right, and I will watch the questions. All right. We have some questions already. 378 00:36:30,125 --> 00:36:41,760 Herald: What do you think about rolling out so-called post-quantum cryptography 379 00:36:41,760 --> 00:36:47,520 now? Natalie: Oh yeah. Post quantum crypto, I 380 00:36:47,520 --> 00:36:54,560 know it's been. It's been a useful concept promised and they have a never specific 381 00:36:55,120 --> 00:37:00,800 problem in mind. And this is for the national security and probably the 382 00:37:00,800 --> 00:37:06,560 government, for infrastructure and in the U.S. specifically. But they're thinking 383 00:37:06,560 --> 00:37:10,240 of, along lived systems, the pig. You see, you have the problem. It's highly 384 00:37:10,240 --> 00:37:15,280 computationally intensive. So a lot of infrastructure can't, can't cope with it. 385 00:37:15,280 --> 00:37:21,440 So we need to deploy other infrastructure. And if you're worried about your data, 386 00:37:21,440 --> 00:37:26,320 you're in the intelligence behind your data being stolen and then, you know, say, 387 00:37:26,320 --> 00:37:33,040 for 20 years. Not many companies have secrets that you can store for that intel 388 00:37:33,040 --> 00:37:39,600 isn't that specific data that data steal and store that is useful. So if you have 389 00:37:39,600 --> 00:37:44,000 data, doesn't intelligence lie for over 20 years yet? It's useful if it's a 390 00:37:44,000 --> 00:37:48,880 government side of, you know, it's a nuclear bomb placed side or something very 391 00:37:48,880 --> 00:37:56,080 critical. Yes, you have to think about it now, and we do need time to implement the 392 00:37:56,080 --> 00:38:01,040 infrastructure. And I mean, the hits close to home. We've heard about crypto agility 393 00:38:01,040 --> 00:38:06,240 to think that we would like to have, but it's it's not the reality. We just have 394 00:38:06,240 --> 00:38:11,280 legacy systems. We have to keep them running. And especially if it's critical 395 00:38:11,280 --> 00:38:14,480 infrastructure, you can just turn it off, build something new and turn it all and it 396 00:38:14,480 --> 00:38:20,640 has to work throughout. So you see is useful for some problems, but not for all. 397 00:38:20,640 --> 00:38:26,960 It's not a one fits all glove. Herald: All right. All right, thank you. 398 00:38:28,560 --> 00:38:36,880 The next question is, you talked about the current number of qubits and how no 399 00:38:36,880 --> 00:38:43,440 practical problem, a lack of the difficult problems that the people are hopeful for 400 00:38:43,440 --> 00:38:50,080 quantum computers to solve. The technology isn't there yet due to the low number of 401 00:38:50,080 --> 00:38:56,640 qubits. Would it make sense to serialize the problems and run them on low qubit 402 00:38:56,640 --> 00:39:05,360 count quantum computers? Does that work? Natalie: I think I might not understand 403 00:39:05,360 --> 00:39:13,680 the question fully, but I assume you mean you package these little programs and I've 404 00:39:13,680 --> 00:39:19,520 shown you the algorithm, the THC, the tensor hyper contraction algorithm that 405 00:39:19,520 --> 00:39:26,720 the chemical guys have used where we do these sort of things. But then again, one 406 00:39:26,720 --> 00:39:33,440 qubit you can think of roughly as one transistor and you just need a couple more 407 00:39:33,440 --> 00:39:40,080 than five or 10 to do meaningful computations, as you've seen. That is a 408 00:39:40,080 --> 00:39:47,120 very good question that we do package these problems into smaller bits. And if 409 00:39:47,120 --> 00:39:53,200 you go back into the slides or look into the the the paper of Nathan Vibha and 410 00:39:53,200 --> 00:39:56,880 Rayen Babbush around because you see that you need still about more than two 411 00:39:56,880 --> 00:40:02,480 thousand logical qubits, so you're spot on. This is the direction that they wanted 412 00:40:02,480 --> 00:40:07,200 to go and we have to go and there to try to. Unfortunately, we still need more than 413 00:40:07,200 --> 00:40:10,924 a couple of hundred. Herald: So are there any current quantum 414 00:40:10,924 --> 00:40:14,568 computers that are programable to do something useful? 415 00:40:14,568 --> 00:40:20,324 Natalie: I mean, it depends really useful. It's very educational to use them. If you 416 00:40:20,324 --> 00:40:26,056 want to have a have a workforce in 10 years that knows how to use them, you need 417 00:40:26,056 --> 00:40:30,600 to do. You need to have, you know, postdocs or master students who know how 418 00:40:30,600 --> 00:40:36,395 to program these things. We need to know how to write better compilers. What are 419 00:40:36,395 --> 00:40:42,731 the what are the bottlenecks, how we can swap gates, quantum gates? Some of these 420 00:40:42,731 --> 00:40:47,764 are operations on a quantum computers. So how we can swap these things and there 421 00:40:47,764 --> 00:40:52,875 that's a useful thing for them to do in any stage are workable quantum computer. 422 00:40:52,875 --> 00:40:57,166 Just a few qubits is still needed to advance the field and to advance the 423 00:40:57,166 --> 00:41:03,262 workforce. So for me, it is still useful. Herald: All right. Yea, it makes sense. 424 00:41:03,262 --> 00:41:10,195 What do you see as candidates for earliest productive uses of quantum computers? 425 00:41:10,195 --> 00:41:15,659 Natalie: Oh, so you mean the question of the killer application for quantum 426 00:41:15,659 --> 00:41:21,680 computers? That's a difficult one. So for cryptography or for optimization of I've 427 00:41:21,680 --> 00:41:29,560 said it before, it's less clear. But for chemistry, once we hit those 20000 or more 428 00:41:29,560 --> 00:41:37,114 logical qubits, we'll see advancements and catalysts. You see it from local molecules 429 00:41:37,114 --> 00:41:42,998 to active side for the nitrogenous to to get ammonia at room temperature. And 430 00:41:42,998 --> 00:41:49,437 that's where I see the advancements for four small catalysts for get alloys and 431 00:41:49,437 --> 00:41:54,633 metals to find better storage batteries. There's there's still a field out there 432 00:41:54,633 --> 00:41:59,619 that we have that we couldn't simulate on classical because it's quite intractable. 433 00:41:59,619 --> 00:42:04,053 But we're pushing the field and I think chemistry could be one of the first ones 434 00:42:04,053 --> 00:42:08,665 that's just not there yet. Herald: All right. Do you also think 435 00:42:08,665 --> 00:42:13,080 that'll be the earliest one's chemistry applications? 436 00:42:13,080 --> 00:42:18,189 Natalie: Small molecules for catalysts? Yes, they could be. I mean, the smarter 437 00:42:18,189 --> 00:42:23,929 people than me out there might have better ideas. Maybe design a completely new 438 00:42:23,929 --> 00:42:28,080 battery storage or I mean, ammonia is being used in fuel cells as well for 439 00:42:28,080 --> 00:42:34,600 storage. Maybe they'll simulate how to get ammonia, cheaper energy expenditure wise 440 00:42:34,600 --> 00:42:42,824 and then use it to store, have better storage and fuel cells yet. I mean, there 441 00:42:42,824 --> 00:42:49,649 are some quantum computing services out there that are kind of interesting depends 442 00:42:49,649 --> 00:42:53,720 what you're looking for. Yes. In Cambridge, quantum computing offers a 443 00:42:53,720 --> 00:42:58,261 three qubit encryption suite if you want to do QCD. I mean, it's a fun toy game. 444 00:42:58,261 --> 00:43:02,801 I'm not sure if it's very business relevant, but if you want to look at your 445 00:43:02,801 --> 00:43:07,424 current infrastructure could hold it. That's an interesting one. Quantum 446 00:43:07,424 --> 00:43:15,597 communication components, especially in that part of the quantum tech world, is 447 00:43:15,597 --> 00:43:22,220 more advanced and more ripe. So a lot of devices in quantum communication you can 448 00:43:22,220 --> 00:43:29,889 use now already. So it's just about your risk appetite. Do you want to, well, spend 449 00:43:29,889 --> 00:43:35,960 a lot of money on it? Do you want to invest into it and try it out? There are 450 00:43:35,960 --> 00:43:42,361 some test beds in Berlin and Paris where they're trying out QKD networks yet. 451 00:43:42,361 --> 00:43:47,061 You know, this is telecom. This is not quantum computing, but it would be the 452 00:43:47,061 --> 00:43:50,493 backbone if we want to have a quantum internet where then again, quantum 453 00:43:50,493 --> 00:43:56,240 computers are useful. So everything is useful because it's it's an intermediate 454 00:43:56,240 --> 00:44:01,932 step towards something you would like to have. But most of the things in quantum 455 00:44:01,932 --> 00:44:06,226 computers, they don't fit classical solutions yet. 456 00:44:06,226 --> 00:44:13,120 Question: All right. You talked about the attack vectors on quantum computers and 457 00:44:14,400 --> 00:44:18,800 dramatizing this a little bit. And what is the worst case of the quantum computer 458 00:44:18,800 --> 00:44:22,080 getting on? Natalie: I mean, worst case is some 459 00:44:22,080 --> 00:44:27,440 company has their sensible business data on it, and they harvest that. I mean, 460 00:44:27,440 --> 00:44:32,400 because they're not, you know, they're not critical components as of yet. And there 461 00:44:32,400 --> 00:44:36,960 are a lot of down times because they have to recalibrate them, you know, get them 462 00:44:36,960 --> 00:44:42,480 off the grid, see if the fridge works or do some sort of maintenance. You don't 463 00:44:42,480 --> 00:44:50,080 have to use usually SLS with them yet, but think about all these companies that don't 464 00:44:50,080 --> 00:44:56,560 know what they're doing, and they might have, you know, the critical data up there 465 00:44:56,560 --> 00:45:02,240 in the cloud pushing it there. And if the API isn't, isn't hard and if it's, you 466 00:45:02,240 --> 00:45:06,880 know, open access for everything, they may just have low hanging fruit to pick out 467 00:45:06,880 --> 00:45:12,880 their. Herald: Thank you so much, Nacho. This was 468 00:45:12,880 --> 00:45:20,640 tales from the quantum industry. Bye Nacho. Thank you. Thank you.
