    Not only can it run it, it could predict the out come of the game based on the first move of the units. Theoretically.

    I still want to know how someone would program a quantum computer. Logically, they don't make sense, at least with the info I've heard about them so far.

    It can both run it and not run it at the same time

    It can play Crysis, it can't play Crysis or it can do both at the same time...

    You have mined 100 bit coins..... you have a 100 bit coin bill to pay. :p

    That was my first thought. Also the same goes for whatever the NSA is using to break crypto.

    so, you can give a quantum computer a question, and it will pretty much be able to instantly give you every possible outcome, but what then decides what the best/correct outcome is?

    it is a probability system. a good example is whit breaking a code it trying 1M codes in one try an while it is calculating it can be code 1 ,2 3 etc but the system must be designed in such a way that the right answer has the highest probability to happen. so if code 10598 is the right answers than it has to have a bigger chance than all other answerers.

    the system collapses at the end of evry calculation so it only gives one answer at the end not 1 maybe 0 but just a plain 1 or 0.

    now repeat the calculations 1000 times and viola the answer is the code you got the most.

    I'm not very smart so this might sound naive: if ordinary (silicon-based) computer takes twice as long as quantum computer to perform a task which provides both answers to a problem with two answers, why not emulate quantum computer in twice (or whichever factor is appropriate) as much hardware ? Why the hassle with liquid nitrogen and the rest of that fancy machinery for something which sounds as trivial as emulating Intel's 4004 on a 80386SX ?
