(upbeat music) >> Narrator: theCUBE's live coverage is made possible by funding from Dell Technologies: creating technologies that drive human progress. (upbeat music) >> Welcome back to the Fira in Barcelona. You're watching theCUBE's Coverage day two of MWC 23. Check out SiliconANGLE.com for all the news, John Furrier in our Palo Alto studio, breaking that down. But we're here live Dave Vellante, Dave Nicholson and Lisa Martin. We're really excited. We're going to talk qubits. Vanessa Diaz is here. She's CEO of LuxQuanta And Antonio Acin is a professor of ICFO. Folks, welcome to theCUBE. We're going to talk quantum. Really excited about that. >> Vanessa: Thank you guys. >> What does quantum have to do with the network? Tell us. >> Right, so we are actually leaving the second quantum revolution. So the first one actually happened quite a few years ago. It enabled very much the communications that we have today. So in this second quantum revolution, if in the first one we learn about some very basic properties of quantum physics now our scientific community is able to actually work with the systems and ask them to do things. So quantum technologies mean right now, three main pillars, no areas of exploration. The first one is quantum computing. Everybody knows about that. Antonio knows a lot about that too so he can explain further. And it's about computers that now can do wonder. So the ability of of these computers to compute is amazing. So they'll be able to do amazing things. The other pillar is quantum communications but in fact it's slightly older than quantum computer, nobody knows that. And we are the ones that are coming to actually counteract the superpowers of quantum computers. And last but not least quantum sensing, that's the the application of again, quantum physics to measure things that were impossible to measure in with such level of quality, of precision than before. So that's very much where we are right now. >> Okay, so I think I missed the first wave of quantum computing Because, okay, but my, our understanding is ones and zeros, they can be both and the qubits aren't that stable, et cetera. But where are we today, Antonio in terms of actually being able to apply quantum computing? I'm inferring from what Vanessa said that we've actually already applied it but has it been more educational or is there actual work going on with quantum? >> Well, at the moment, I mean, typical question is like whether we have a quantum computer or not. I think we do have some quantum computers, some machines that are able to deal with these quantum bits. But of course, this first generation of quantum computers, they have noise, they're imperfect, they don't have many qubits. So we have to understand what we can do with these quantum computers today. Okay, this is science, but also technology working together to solve relevant problems. So at this moment is not clear what we can do with present quantum computers but we also know what we can do with a perfect quantum computer without noise with many quantum bits, with many qubits. And for instance, then we can solve problems that are out of reach for our classical computers. So the typical example is the problem of factorization that is very connected to what Vanessa does in her company. So we have identified problems that can be solved more efficiently with a quantum computer, with a very good quantum computer. People are working to have this very good quantum computer. At the moment, we have some imperfect quantum computers, we have to understand what we can do with these imperfect machines. >> Okay. So for the first wave was, okay, we have it working for a little while so we see the potential. Okay, and we have enough evidence almost like a little experiment. And now it's apply it to actually do some real work. >> Yeah, so now there is interest by companies so because they see a potential there. So they are investing and they're working together with scientists. We have to identify use cases, problems of relevance for all of us. And then once you identify a problem where a quantum computer can help you, try to solve it with existing machines and see if you can get an advantage. So now the community is really obsessed with getting a quantum advantage. So we really hope that we will get a quantum advantage. This, we know we will get it. We eventually have a very good quantum computer. But we want to have it now. And we're working on that. We have some results, there were I would say a bit academic situation in which a quantum advantage was proven. But to be honest with you on a really practical problem, this has not happened yet. But I believe the day that this happens and I mean it will be really a game changing. >> So you mentioned the word efficiency and you talked about the quantum advantage. Is the quantum advantage a qualitative advantage in that it is fundamentally different? Or is it simply a question of greater efficiency, so therefore a quantitative advantage? The example in the world we're used to, think about a card system where you're writing information on a card and putting it into a filing cabinet and then you want to retrieve it. Well, the information's all there, you can retrieve it. Computer system accelerates that process. It's not doing something that is fundamentally different unless you accept that the speed with which these things can be done gives it a separate quality. So how would you characterize that quantum versus non quantum? Is it just so much horse power changes the game or is it fundamentally different? >> Okay, so from a fundamental perspective, quantum physics is qualitatively different from classical physics. I mean, this year the Nobel Prize was given to three experimentalists who made experiments that proved that quantum physics is qualitatively different from classical physics. This is established, I mean, there have been experiments proving that. Now when we discuss about quantum computation, it's more a quantitative difference. So we have problems that you can solve, in principle you can solve with the classical computers but maybe the amount of time you need to solve them is we are talking about centuries and not with your laptop even with a classic super computer, these machines that are huge, where you have a building full of computers there are some problems for which computers take centuries to solve them. So you can say that it's quantitative, but in practice you may even say that it's impossible in practice and it will remain impossible. And now these problems become feasible with a quantum computer. So it's quantitative but almost qualitative I would say. >> Before we get into the problems, 'cause I want to understand some of those examples, but Vanessa, so your role at LuxQuanta is you're applying quantum in the communication sector for security purposes, correct? >> Vanessa: Correct. >> Because everybody talks about how quantum's going to ruin our lives in terms of taking all our passwords and figuring everything out. But can quantum help us defend against quantum and is that what you do? >> That's what we do. So one of the things that Antonio's explaining so our quantum computer will be able to solve in a reasonable amount of time something that today is impossible to solve unless you leave a laptop or super computer working for years. So one of those things is cryptography. So at the end, when use send a message and you want to preserve its confidentiality what you do is you destroy it but following certain rules which means they're using some kind of key and therefore you can send it through a public network which is the case for every communication that we have, we go through the internet and then the receiver is going to be able to reassemble it because they have that private key and nobody else has. So that private key is actually made of computational problems or mathematical problems that are very, very hard. We're talking about 40 years time for a super computer today to be able to hack it. However, we do not have the guarantee that there is already very smart mind that already have potentially the capacity also of a quantum computer even with enough, no millions, but maybe just a few qubits, it's enough to actually hack this cryptography. And there is also the fear that somebody could actually waiting for quantum computing to finally reach out this amazing capacity we harvesting now which means capturing all this confidential information storage in it. So when we are ready to have the power to unlock it and hack it and see what's behind. So we are talking about information as delicate as governmental, citizens information related to health for example, you name it. So what we do is we build a key to encrypt the information but it's not relying on a mathematical problem it's relying on the laws of quantum physics. So I'm going to have a channel that I'm going to pump photons there, light particles of light. And that quantum channel, because of the laws of physics is going to allow to detect somebody trying to sneak in and seeing the key that I'm establishing. If that happens, I will not create a key if it's clean and nobody was there, I'll give you a super key that nobody today or in the future, regardless of their computational power, will be able to hack. >> So it's like super zero trust. >> Super zero trust. >> Okay so but quantum can solve really challenging mathematical problems. If you had a quantum computer could you be a Bitcoin billionaire? >> Not that I know. I think people are, okay, now you move me a bit of my comfort zone. Because I know people have working on that. I don't think there is a lot of progress at least not that I am aware of. Okay, but I mean, in principle you have to understand that our society is based on information and computation. Computers are a key element in our society. And if you have a machine that computes better but much better than our existing machines, this gives you an advantage for many things. I mean, progress is locked by many computational problems we cannot solve. We can want to have better materials better medicines, better drugs. I mean this, you have to solve hard computational problems. If you have machine that gives you machine learning, big data. I mean, if you have a machine that gives you an advantage there, this may be a really real change. I'm not saying that we know how to do these things with a quantum computer. But if we understand how this machine that has been proven more powerful in some context can be adapted to some other context. I mean having a much better computer machine is an advantage. >> When? When are we going to have, you said we don't really have it today, we want it today. Are we five years away, 10 years away? Who's working on this? >> There are already quantum computers are there. It's just that the capacity that they have of right now is the order of a few hundred qubits. So people are, there are already companies harvesting, they're actually the companies that make these computers they're already putting them. People can access to them through the cloud and they can actually run certain algorithms that have been tailor made or translated to the language of a quantum computer to see how that performs there. So some people are already working with them. There is billions of investment across the world being put on different flavors of technologies that can reach to that quantum supremacy that we are talking about. The question though that you're asking is Q day it sounds like doomsday, you know, Q day. So depending on who you talk to, they will give you a different estimation. So some people say, well, 2030 for example but perhaps we could even think that it could be a more aggressive date, maybe 2027. So it is yet to be the final, let's say not that hard deadline but I think that the risk, that it can actually bring is big enough for us to pay attention to this and start preparing for it. So the end times of cryptography that's what quantum is doing is we have a system here that can actually prevent all your communications from being hacked. So if you think also about Q day and you go all the way back. So whatever tools you need to protect yourself from it, you need to deploy them, you need to see how they fit in your organization, evaluate the benefits, learn about it. So that, how close in time does that bring us? Because I believe that the time to start thinking about this is now. >> And it's likely it'll be some type of hybrid that will get us there, hybrid between existing applications. 'Cause you have to rewrite or write new applications and that's going to take some time. But it sounds like you feel like this decade we will see Q day. What probability would you give that? Is it better than 50/50? By 2030 we'll see Q day. >> But I'm optimistic by nature. So yes, I think it's much higher than 50. >> Like how much higher? >> 80, I would say yes. I'm pretty confident. I mean, but what I want to say also usually when I think there is a message here so you have your laptop, okay, in the past I had a Spectrum This is very small computer, it was more or less the same size but this machine is much more powerful. Why? Because we put information on smaller scales. So we always put information in smaller and smaller scale. This is why here you have for the same size, you have much more information because you put on smaller scales. So if you go small and small and small, you'll find the quantum word. So this is unavoidable. So our information devices are going to meet the quantum world and they're going to exploit it. I'm fully convinced about this, maybe not for the quantum computer we're imagining now but they will find it and they will use quantum effects. And also for cryptography, for me, this is unavoidable. >> And you brought the point there are several companies working on that. I mean, I can get quantum computers on in the cloud and Amazon and other suppliers. IBM of course is. >> The underlying technology, there are competing versions of how you actually create these qubits. pins of electrons and all sorts of different things. Does it need to be super cooled or not? >> Vanessa: There we go. >> At a fundamental stage we'd be getting ground. But what is, what does ChatGPT look like when it can leverage the quantum realm? >> Well, okay. >> I Mean are we all out of jobs at that point? Should we all just be planning for? >> No. >> Not you. >> I think all of us real estate in Portugal, should we all be looking? >> No, actually, I mean in machine learning there are some hopes about quantum competition because usually you have to deal with lots of data. And we know that in quantum physics you have a concept that is called superposition. So we, there are some hopes not in concrete yet but we have some hopes that these superpositions may allow you to explore this big data in a more efficient way. One has to if this can be confirmed. But one of the hopes creating this lots of qubits in this superpositions that you will have better artificial intelligence machines but, okay, this is quite science fiction what I'm saying now. >> At this point and when you say superposition, that's in contrast to the ones and zeros that we're used to. So when someone says it could be a one or zero or a one and a zero, that's referencing the concept of superposition. And so if this is great for encryption, doesn't that necessarily mean that bad actors can leverage it in a way that is now unhackable? >> I mean our technologies, again it's impossible to hack because it is the laws of physics what are allowing me to detect an intruder. So that's the beauty of it. It's not something that you're going to have to replace in the future because there will be a triple quantum computer, it is not going to affect us in any way but definitely the more capacity, computational capacity that we see out there in quantum computers in particular but in any other technologies in general, I mean, when we were coming to talk to you guys, Antonio and I, he was the one saying we do not know whether somebody has reached some relevant computational power already with the technologies that we have. And they've been able to hack already current cryptography and then they're not telling us. So it's a bit of, the message is a little bit like a paranoid message, but if you think about security that the amount of millions that means for a private institution know when there is a data breach, we see it every day. And also the amount of information that is relevant for the wellbeing of a country. Can you really put a reasonable amount of paranoid to that? Because I believe that it's worth exploring whatever tool is going to prevent you from putting any of those piece of information at risk. >> Super interesting topic guys. I know you're got to run. Thanks for stopping by theCUBE, it was great to have you on. >> Thank you guys. >> All right, so this is the SiliconANGLE theCUBE's coverage of Mobile World Congress, MWC now 23.
