Preskill: Validated topological qubit may appear as soon as 2019
“And it's very ambitious, because at this point, it's not even clear they have a single qubit, but if that approach is successful, and we're, it's making progress, so I think we will see a validated Qubit of this type soon, maybe next year.”

Preskill: Superconducting circuits and trapped ions will lead for 5-10 years
“The most advanced are superconducting circuits and trapped ions, which is why I mentioned those first, and I think that will remain true, you know, over the next five to 10 years.”

Preskill: Quantum computers will impact chemistry, carbon capture, and materials
“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 …”

Preskill: 50-to-100 qubit quantum computers will arrive in a couple years
“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…”

Preskill: Quantum computers breaking public key crypto unlikely in 10 years, likely in 50
“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.”

Preskill: Efficient classical algorithms for quantum chemistry are unlikely
“Maybe some brilliant graduate student is going to drop a paper on the archive tomorrow which will say, here I solve quantum chemistry and I can do it on a digital computer. But we don't think that's very likely because we've been working pretty hard on these p…”

Preskill: Near-term quantum computing has best hopes in hybrid classical-quantum methods
“Well, I think in the near term, we're going to be trying out, and probably we have the best hopes for kind of hybrid classical quantum methods with some kind of classical feedback.”

Preskill: Silicon electron spin qubits could surpass other modalities long-term
“In the long term those electron spins could catapult ahead of these other things. That's something that you can naturally do in silicon, and you know, it's potentially easy to integrate, integrate with silicon technology.”

Preskill: Quantum error correction is now achievable in the laboratory
“But at first that was just kind of a theorist fantasy. It was a little too far ahead of The technology, but, you know, 20 years later, the technology is catching up, so now this idea of quantum error correction has become something you can do in the lab.”

Preskill: Grover's algorithm only doubles tractable cities in traveling salesman problems
“And in practice, it's not that big a deal. What it means is that, you know, if you have the same processing speed, you can handle about you know, twice as many cities before the problem becomes too hard to solve as you could if you were using a classical proce…”

Preskill: Current quantum computers are too small for proposed algorithms
“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.”
