What advancements could quantum computing provide for future videogames?

Would CPUs and GPUs be more powerful, resulting in realistic game physics and unlimited AI? What other effects could we potentially see? I'm new to the ideas and potential of quantum computing.

Quantum computers produce probabilistic results. That is, if you ask it to add 2+2 you might get something close to 4 with error bars. Software written for a normal Turing machine (e.g. Crysis) probably won't ever transition well to a machine that is technically bad at basic math.

Quantum computers are not even currently particularly fast and do not threaten encryption through raw power. They also can't really check every possible outcome at once, although Grover's algorithm can do something sort of conceptually similar where it checks O(N) possible encryption keys in O(N)^1/2 operations. 

Unless you are doing specialized math or cryptography and you're okay with a small chance that your computer will give you the wrong answer, then you probably don't ever want a quantum computer.
