That’s not really something that’s on the horizon at all. There’s some experimental quantum computing stuff, but it’s not really practical for anything yet (and certainly not in a personal computer!) It’s also likely not going to be better at the stuff we use normal CPUs for. Eventually they might be useful for certain classes of problems, but probably in more of a coprocessor like capacity (kind of like a side unit like a GPU that’s good at certain tasks). Obviously it’s unknown what the future holds, but I don’t think quantum computing is going to replace silicon any time soon.
