No, post-quantum cryptography is focused on methods where encryption can be done with classical computers. Post-quantum methods have other disadvantages, primarily that they haven't been studied as deeply as traditional methods (especially RSA) so they may be vulnerable to classes of attack we haven't thought of yet. https://en.m.wikipedia.org/wiki/Post-quantum_cryptography https://en.m.wikipedia.org/wiki/Post-quantum_cryptography
