Not one current crypto system will be safe?
Surely that depends on the nature of the cryptographic scheme?
Anything based on long random numbers should be fine, But distributing
them has always been a problem. Public key encryption with pairs of
really long keys could take a very long time to crack even with quantum computers.
Every quantum computer has problems with internal random errors, and has
to rely on error detection and correction codes to manage them.
Make your numbers long enough and the quantum computer won't be quick
enough to stay ahead.
