Can quantum computers attack crypto in ways that current supercomputer clusters can't? Yes. 3/13

But quantum computers don't exist yet (as far as we know), and they can only meaningfully attack some crypto algorithms -- typically public key algorithms. Except for rare edge cases, symmetric crypto remains mostly unaffected. 4/13

There is an active domain of research called 'post-quantum cryptography'. It is populated by mathematicians and computer scientists, who develop cryptography that can serve as a drop-in replacement for the affected algorithms. 5/13
