Quantum computation is a distinctively new way of harnessing nature. It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes.

Science is objective. And in my view we cannot take any experimental results seriously except in the light of good explanations of them.

If you can’t program it, you haven’t understood it.

Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow.

Discovering a new explanation is inherently an act of creativity.

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.

Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests.

The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.

Our best theories are not only truer than common sense, they make more sense than common sense...
