Current SSL is 128-bit, and it'll be a LONG time before a quantum computer is made that can crack that quickly (you'd need about a 129 qubit quantum computer). If we get close to that, make SSL 1024 bits and the quantum computer builders will have to catch up again. But when the time comes, quantum physics solves the problem it creates, using quantum encryption.
As a programmer, I've gone from 1KB RAM to 1GB RAM - 6 orders of magnitude in just two decades.
We're at 16 qbits right now.
16Mqb 20 years from now is not an unreasonable prediction.
1024 bit SSL will be a cute anachronism then.
Heck, 1024 bit SSL may be a cute anachronism some time next year (that would only need a 32x32 qbit quantum computer, and we're at 4x4 now).
