Would you be able to give any examples of quantum resistant encryption algorithms? I'm not familiar with the field and my most recent knowledge is a post on hn saying that some post quantum candidates had been broken by old laptops.
The whole symmetric key cryptography (e.g. AES) ia already quantum resistant. The problem only holds for public key encryption, but as the other commenter pointed out, there are already promising algorithms.
I'm not an expert in the field, but there is already a NIST competition going on to stansardize post-quantum public key ciphers. So I would say that we're at a good point in post-quantum cryptography development.
