Quantum Computer

“It's very interesting when you look at these long-dated technologies. All roads converge to 2030. It's like quantum computing, utility scale, logically error-corrected, million-qubit quantum computer, twenty-thirty.”

“If you did have a computer powerful enough to crack these encryptions, unless you were like, Google and you already had billions and billions and billions of dollars of cash flow. You wouldn't exactly stand up and say like, Hey, I have cracked Bitcoin because …”

“Our this announcement of yesterday is a paper in nature that that actually shows the first verifiable practical application advantage of a quantum computer over classical computer.”

“We published this quantum supremacy experiment with 53 qubits, where we made a lot of qubits, and we made them really good, and, you know, fast and whatever, so that we could run some algorithm, mathematical algorithm, that what, we produced some output that w…”

“They aren't really big enough to be useful yet. They have to get bigger, and they have to get better. Less noise.”

“And because of that, you're talking about a million qubit quantum computers to be general purpose and solve really hard problems. There might be some million. A million is a good round number for it. Maybe a little bit more. And right now we're at, you know, a…”

“The goal would be to get to a thousand error corrected qubits, right? But just from that perspective, that's going to be around seven million physical qubits to do that.”

“I think you'll see in 20, 27, 20, 28, the first hundred air created qubits on fast machines.”

“In around 2040, we think there'll be enough qubits to start to break encryption, and secrets last longer than that.”

“The general consensus is that you need more like a million qubits to do anything commercially impactful with a quantum computer.”

“Our conventional supercomputers suck at predicting the properties of these microscopic things. And that happens to be exactly the set of problems where a quantum computer is perfectly suited and where we will solve problems that can never be solved by any conv…”

“Quantum computing is the same, right? Like most people will never program a quantum computer. Most people will never directly interact with a quantum computer.”

“As far as we understand still, despite these new architectural results, algorithmic results, you still need a bigger computer to do code breaking than you do to tackle the commercially useful applications that we talked about earlier.”

“When you're making a ton of revenue you're probably doing something that, you know, within reason you could call useful and like a billion dollars of revenue would be a nice starting point for a useful machine like this. Yeah, definitely what is not useful is …”

“I, you know, who knows how, how people are going to write software in 10 years, like for what, for quantum computers, for You know, and it's just like you might have a business today. It's like building a castle on sand, right? Like it's just very, very hard t…”

“Look, we'll have to figure that out because that'll be an issue once we get to what is, you know, somewhere maybe minimum 2000 or 5000 logical quantum bits, qubits. So that's at 2000 to 5000 or more is when you get into the encryption issues. I'd call it a 150…”

“We're encrypting data using Linear algorithms that are trivially defeatable with commercially viable quantum computers.”

“I believe that that's where technology is, is, is heading and in the language of abundance as well, where, what the technology is going to provide us because of that.”

“Industry availability of these computers would take at least three years. We estimate three to five years”

“And this is the challenge that a quantum computer can solve in an ultimate state, because it's able to solve all those things in parallel versus doing something in series. And so problems get really, really challenging when you have permutations that grow at a…”

“DeepMind actually just released some really interesting papers on how they can predict, based on the sequence of amino acids, how a protein can fold. A quantum computer will be able to do that better. It just will”

“And so I am highly optimistic that by within this decade for sure, we will have meaningful impacts from quantum computers. And I can imagine in the next three to five years we are going to see winners emerge with very specific use cases that are going to shock…”

“I do think it is going to be those optimization problems, honestly. I really think it's going to be in transportation, I think it's going to be in optimization because that problem is far more definable, it is easier, it takes a lower power quantum computer, T…”

“Quantum computers are ever built. Yes, they will be able to affect the signature algorithm that's used for securing assets on blockchains today, but not to worry. We have other signature algorithms that are actually quantum resistance. So even if you have a qu…”

“The estimate currently by some researchers is that this there's a less than five percent chance this happens before the year 2040. So we're talking somewhere between the year 2040 and the 2060. When we get a quantum computer that has enough logical qubits to b…”

“Over the next hundred next 10 years or so, the current super noisy, super low fidelity quantum computers can be used to simulate quantum states, which is the condition of atoms and molecules, and use that to do better modeling of physiochemical properties of m…”

“Unlike classical computers, which you can kind of run for days and weeks, Or in perhaps years at a time, quantum computers kind of run in bursts of a hundred microseconds.”

“Quantum computers can actually search combinatorially a huge space for certain kinds of problems and actually find the real thing that nature would do.”

“What will happen is a quantum computer at first will seem like it won't be all that useful. It will be below the number of qubits that you need. Maybe you need a hundred qubits to solve the problem and the existing machine only has 64. And so a classical compu…”

“Building cloud access into how you get at a quantum computer will quicken the pace at which the killer apps are found instead of there being one, like there was in the early days of the PC and electronic spreadsheet, we might see a half a dozen of them pop up …”

“Like, you can't actually store data on these quantum computers. They're just literally, right now, just compute engines.”

“So you never really, at least in the early days, want to ever put those things, on a customer site, you want to put them in a secure facility someplace and provide cloud access or remote access to them.”

“Or enzymes. It's all the chemistry, you know, so, so this is something where a quantum computer could be able to do calculations that are either much bigger at much higher accuracy where actually would be essentially much bigger at higher, much much higher acc…”

“One of the surprising aspects of quantum computing is that scientists and mathematicians and computer engineers don't really know all of the problems that can be solved by a quantum computer. We just know some of them, and that's not How classical computing wo…”

“And with a quantum computer, if you have a hundred qubits and you add one more, you don't have a one percent performance increase, you double the performance. And that persists independent of the memory size. So every quantum bit you add to the system doubles,…”

“And part of what that implies is that you need to build a very sophisticated Classical computer around the quantum computer to both leverage its resources and to offload anything from that quantum computer that can be offloaded so that the quantum computer is …”

“And a quantum computer, even with a modest number of qubits, and the analogy that gets banded around by everybody who's been on the D-Wave website, or who's read all these articles, Is that a Quantum computer with 40 or 50 entangled qubits would be more powerf…”

“We're not there yet, by the way, but when we get there, these machines will have an amazing capacity to solve these types of problems. One of the applications from that would be the quick and careful analysis of our DNA, and the creation of designer drugs.”

“All the world of crypto that we use on the internet today, and for Bitcoin as well, ah, would be well, would be broken if someone was able to build a quantum computer.”

“I would speculate that in my lifetime, We'll probably see some sort of a, of operating quantum computer.”

“The entire hope of getting a speed advantage from a quantum computer is to exploit the way that amplitudes work differently. It's to try to choreograph a pattern of interference Where for each wrong answer to your computational problem, like some of the paths …”

“What changed everything for most of us in the nineties was the discovery of quantum error correction, right? And quantum fault tolerance. The upshot of which was if you want to build a scalable quantum computer, you don't need to get perfect qubits. That are p…”

“Maybe the most important application that we know about is just giving us this new way to simulate nature, simulate physics and chemistry, and maybe discover new drugs, discover new materials, right?”

“Especially something called the Kataev surface code, which is, at the moment, the go-to solution for how we would build a quantum computer.”

“So, 45 qubits required 0.5. This wasn't my work. This was work elsewhere in the community. It required 0.5 half a petabyte of RAM, basically.”

“There's no point, if you think you've got a clever idea for what to use a quantum computer for, and that's going to change the world, if your idea involves much less than 50 qubits, you're wrong. Because, ah, you may have a very nice idea, but what we would do…”

“What we've worked out on paper is stuff that needs pretty big computers, and we don't know how long it would take to get there. You know, maybe, hopefully not decades, but it could take definitely more than a decade to get to the point where we have millions o…”

“And in fact, this network approach is, I think the only one that if you wanted to Manhattan project it, right, or moonshot it, you're one of these big projects that have happened in the past where you have a goal that's extremely challenging and you just decid…”

“The Ones which will affect everyday life, I think, are better methods for understanding and inventing new materials, new chemical compounds. Things like that can be really important. You know, if you find a better way of capturing carbon by designing a better …”

“We have algorithms that have been proposed, but, which we can't really run currently, because our quantum computers aren't big enough, on the scale that's needed to solve problems really, people really care about.”

“We think in a couple of years we'll have devices with about 50 qubits to a hundred, and we'll be able to control them pretty well, and that's an interesting range, because even though it's only 50 to a hundred qubits, doesn't sound like that big a deal, but th…”

“RSA, which is one of the ones that's widely used, as typically practiced today, the, to break it, you'd have to do something like factor a number, which is Over 2000 bits long to 20 48. And that's, you know, that's too hard to do now. But that's what quantum c…”

“I don't think, though I could be wrong, that we're likely to have quantum computers that can break those public key cryptosystems in 10 years. But in 50 years? Seems not unlikely.”

“So we built single atom resolution electron microscopes, which turns out to be very similar to building quantum computers. And that you're manipulating the quantum states of individual atoms, but use that for biotechnology purposes.”

“Now, if you listen to the prime minister, he implied that what we were trying to do with quantum computers was make smaller computers. And while he didn't say anything technically inaccurate, I think that misses the point a little. So we're not really trying t…”

“What we're really trying to do is build quantum computers that can solve a class of mathematical problems that we couldn't solve with traditional computers or that we could only solve with way big amounts of memory and would take a long, long, long, long time.”

“Instead of performing Boolean algebra operations, in quantum computers, what we're using is a set of quantum gates, and they implement quantum operations, and the way to think about this is as linear algebra operations.”

“Most quantum computers are cooled to 0.1 degrees Kelvin to minimize their interactions with the outside world.”

“So if we had a quantum computer, we could dramatically reduce the time it Took to recover the prime factors and all of modern crypto that we're using today would instantly be susceptible to attack because it wouldn't take a long, long time to decrypt somebody'…”
