With quantum computing comes a fundamental shift. The ability to spin up and down, to hold multiple states in superposition, to become entangled -all this is what atoms naturally do. Performing a quantum computation is a matter of jumping on the wagon and going along for the ride.
So maybe this kind of computing has always been going on. The particles that have been bouncing around since creation, fiipping each other’s sping, exchanging information, have been performing some kind of great cosmic calculation. The universe might itfself be a quantum computer. But that is another book.
