Funny research paper co-authored by Daniel J. Bernstein, "Post-quantum RSA", explores potential "parameters for which key generation, encryption, decryption, signing, and verification are feasible on today’s computers while all known attacks are infeasible, even assuming highly scalable quantum computers".
Funny part is that the actual parameters are "really" practical. Example: "For the 2Tb (256GB) encryption, the longest multiplication took 13 hours, modular reduction took 40 hours, and in total encryption took a little over 100 hours."
