Science consists exactly of those forms of knowledge that can be verified and duplicated by anybody.

In order to figure out how to make atoms compute, you have to learn how to speak their language and to understand how they process information under normal circumstances.

When you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.

Thinking of the universe as a computer is controversial.

At some point, Moore's law will break down.

Quantum mechanics is just completely strange and counterintuitive. We can't believe that things can be here [in one place] and there [in another place] at the same time. And yet that's a fundamental piece of quantum mechanics. So then the question is, life is dealing us weird lemons, can we make some weird lemonade from this?

The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
