The IETF is working on addressing the threats to classic cryptography posed by quantum computing. By design, the IETF does not define new cryptography and focuses on standardizing protocol behavior.
The non-WG mailing list pqc@ietf ([https://www.ietf.org/mailman/listinfo/pqc subscribe] | [https://mailarchive.ietf.org/arch/browse/pqc/ archive]) is a forum in which to discuss this topic in the IETF.
