Will quantum programs exhibit all possible bugs as well as correct behavior?

New theory: quantum computers are just cloud computers that steal computing cycles from other people's universes.

I jest, but seriously, just the idea of theses things trips me up in the head. It's neat to see 'wacky' physics put to practical use.

The irony is that that's not far from the reason that they were first conceptualized.

David Deutch is a proponent of the multiverse interpretation of quantum mechanics and originally came up with the notion of quantum computing as an experiment that could ideally prove the truth of the multiverse interpretation by solving a problem large enough that it would not be tractable in one universe.

So when my quantum computer is slow, does it mean that most of the alternate versions of myself are playing Cryis instead of working? :)

The idea of solving a problem too big to be solved in one universe is really crazy, it reminds my of Asimov's "The Last Question".

this is my understanding. the other states do exist, just not in our universe.

As cool as this is, sadly, I don't think we'll be seeing those processors in mainstream computers for a couple of decades.

It's the first processor that works and also doesn't. ;-)
