It's nice to now have a short post by Bruce Schneier I can point to every time someone comes up with "public key crypto is doomed because of quantum computers" FUD: schneier.com/blog/archives/201
He's referencing the earlier "factorizing RSA with a 20-million qubit quantum computer" paper, and notes that we're not anywhere near being able to build such a computer. So, yes, RSA is still doomed eventually, but not before some considerable technology leap happens. Quite a way from 100 qbits to 20 million.

@galaxis
I am currently more worried about world governments outlawing strong crypto than I am of obsolescence based on quantum computing.

@ScottMortimer Same. "Crypto is secure either for everyone, or for nobody" was a hard enough sell to the previous generation of politicians, and before there were the resources and technology to just grab up all communication.
