content: im sorry, i didnt think we have quantum anything at the moment. would it not be silly then to claim something is protected from a technology we havent even achieved yet?  It's not as silly as it sounds. As far as I know, we don't have practical QCPUs but we do have hybrid machines. It's just a matter of adding a few more qubits in the system. Then, if we can't solve p vs np outright, then a probabilistic state machine would at least lower the brutes needed to brute force an NP problem. The point is, even if there isn't a threat now, that could easily change and you don't want to wait until after the network breaks to have security in place. Because, when the network breaks, everything is worthless.
