Most buzz about quantum computers is how they might be able to break traditional encryption algorithms by fast defactorisation of very big numbers. Though they still owe us proof, that this actually works.
There is this paper, which compares the “big” achievements in quantum defactorisation with a (not really) trained dog. Basically every of these achievements cheated with the prior knowledge of the factors or have chosen convenient numbers, while still being worlds away from common key sizes (like 2048 or 4096 bit).
Real usage for quantum cpmputers will probably still take quite a while to manifest.
