Hopefully we work around this, encryption is more important now than ever.
Doesn't the existence of key collision help? If you throw a quantum brute force algorithm at a ciphertext, wouldn't you get a long list of keys, all of which authenticate and appear to work, but for all but one of those keys, what it decrypts to is garbage?
Authentication itself is fucked, but encryption is only heavily weakened rather than completely destroyed.
Yeah but that's precisely the problem. Cut the list down to say a million choices vs quadrillions, and have a regular lower power server work through that much smaller list.
Don't forget, this is gen 1 of the quantum systems as well... Who knows what the future holds. Better to make the lock strong now.
