@ambiguous_yelp @dalias @sammi @joelanman Quantum computing will not be a threat to cryptography any time soon. It might be in the far future, but not now. Post quantum cryptography isn't useless though, it's good to prepare for a threat before it happens, but the threat is also far away right now & not urgent.
Cryptographers could also be completely wrong about quantum computing as a threat & how to defeat it. Just watch there be a zero day exploit in common post quantum cryptography algorithms four hours after consumer quantum computing is made available.
