Gah.

QC does not ruin cryptography. It doesn't even significantly threaten it. In some cases it offers better time complexity than the best-known classical algorithms, but even if some hypothetical QC machine clocks as fast as the fastest classical computer available, in the worst case you have to double your key lengths to achieve the same work factor.

Might as well worry about sorcery breaking encryption.
