    It does and many security or privacy oriented services have already implemented post quantum encryption, but majority of the internet still relies on AES-256 or similar if not worse.

      AES-256 is fine actually. The best known quantum attack reduces key strength from 256 bits to 254.4 bits. The problem is that in order to use AES (which is a symmetric encryption scheme) you need to exchange keys using an asymmetric system like RSA, which is known to be weak to quantum attacks.
