“Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices…If you can figure out how to take advantage of this quantum multitasking, we can build computers that can do computations that no classical computer could do even if it were the size of the entire universe.”

Context: Quantum computation is … nothing less than a distinctly new way of harnessing nature … It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes, and then sharing the results.
