? You might not think that quantum cryptography is likely to be practical soon. But it is definitely resistant to quantum computers.

My point was that quantum cryptography doesn't solve anything that classic cryptography doesn't. (And yes there is classic cryptography that isn't broken by quantum computers.) I'll defer to two of the world's leading cryptographers to back me up:

I disagree for two reasons.
First, because there is a huge difference between having a single quantum computer and quantum computers in every household.
Second, because we don't need quantum cryptography, we need post-quantum cryptography. Quantum computers break only asymmetric cryptosystems, but despite common belief, quantum cryptography doesn't solve this! Post-quantum cryptography does, and there is already good promise in this field.
