Games aren't really an area that would benefit directly from Quantum computing. The benefit is for other fields, like mathematics, communication, cracking encryption, physics. Quantum does not mean faster, it means they operate in a fundamentally different way and have different applications. Just like the stack of IBM QS22 Cell Blades next to me (Which don't even have video cards), they are for a totally different purpose and in some cases even if they could run a normal game might even be slower. High-Performance-Computing is a very different field, and it has to be specifically programmed for, which is why the article mentions they are advancing the new SDKs to allow things to run.
My computers don't even have a real "OS", they have micro kernels which only have one program installed, and that program is specifically crafted to fit inside the 256KB of L2 Cache on the IBM Cell Processor to prevent the system having to page regular, slow, system RAM.
The stuff is written in C, and then hand-tuned in assembler.
That does not mean the development is not exciting, its just that like most major science changes, the action is far from the end user and it will take products a while to trickle down to something we use everyday. Ironically, by the time it gets to us, most people will have no idea which technologies brought them to fruition in the first place.
