From what i heard, even 1,000 qubits isn't close to enough for modern passwords: https://www.nature.com/articles/d41586-023-00017-0

Paywall. Also, passwords and RSA are two different things.

Reversing hashing algos is what people mean when they talk about quantum computers cracking passwords / encryption, though.

[–] frezik@midwest.social 4 points 11 months ago

No, they mean breaking RSA. The industry standard methods of storing passwords are resistant to QC attacks. Passwords could be broken while being passed between client and server under existing algorithms, but not the databases they're stored in.
