“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 hundred or, you know, a little bit more than that.”

Martinis: Current quantum computers are not big or reliable enough yet
“They aren't really big enough to be useful yet. They have to get bigger, and they have to get better. Less noise.”
Martinis: Useful quantum computers will arrive in 8 to 10 years
“And what we want to do, and it's a timeline of many other groups, is to do something in, let's say in the next eight, 10 years, something like that.”
