Its more of a problem if you have key exchange (like RSA); here [1] it says that with AES is supposedly secure against quantum computers with 'sufficiently sized key sizes'; For key exchange they are trying to adapt elliptic curves.

- snakeanus 10y agoElliptic curves are broken in a quantum setting.
- ekiru 10y agoThere is an approach (called Supersingular isogeny Diffie-Hellman or SIDH) using certain types of mappings between elliptic curves being researched that _may_ be secure in a quantum setting. (edit to add:) I think this may be what the grandparent poster is referring to by "trying to adapt elliptic curves".
