Comment on Regarding this picture, where do you think quantum computers lie and why?

…and cryptography.

I think I’m a typical consumer, and if I’m not mistaken we use cryptography constantly (https and banking, off the top of my head). If quantum computers are important for cryptography, it’s hard to imagine “regular people” having no use.

Imagine quantum PCs get usable and we don’t update users cryptography 😂 you could as well communicate in plain text in that case

Cryptography is most of the hype I’ve heard. It’s usually something along the lines of imagine all encryption/certificates being breakable instantly

  That’s not the case, quantum computing can only break specific types of cryptography.

Specifically breaking prime number based cryptography.

Your use of Cryptography is probably roughly on the level of “Having a strong password.”

The application of quantum computers will largely in in BREAKING security. You’re not going to have a quantum-security module in your phone or home computer.

  Not necessarily we could get better more complex security at boot with a qbit TPM chip. Every time you log into a secure boot environment you are solving a hash which is in the wheelhouse of quantum compute.
