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

Thinking of the universe as a computer is controversial.

There are considerable advantages to using many degrees of freedom to store information, stability and controllability being perhaps the most important.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

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.
