One question though, to anyone more up to date than myself on quantum computing:
Even though you can control the state of the photon you send into the system - you can decide to put it into a superposition - how can you control what the computer does, since the thing technically is shut down? Or do you just start (no, no pun intended) the process and hope for the best?

Presumably, the computer is not shut down completely otherwise there would be no means by which to view the answer. Maybe the series of commands is known but not "run" and so you get the answer whether you run the command or not. Quite startling really, but not the weirdest occurrence in the quantum world.
