The prior thread on Quantum tag reform did not discuss quantum-resistance, and there are many more questions tagged post-quantum-cryptography. The dominant nomenclature seems to be post-quantum, not quantum-resistant—see, e.g., https://pqcrypto.org/, the NIST PQC project, the PQCrypto conference, etc.
The tag wiki reads
Some conventional, standardized algorithms are quantum-resistant without being explicitly designed for it. A notable example of this is AES, which is widely considered to be secure against attacks with quantum computers if a key size of 256 bits is used.
but this distinction doesn't seem to make much of a difference—it's not clear to me that this is helpful for sorting questions, and it's less clear that there's been any adherence to this distinction in the tag usage.
Does the quantum-resistance tag serve a useful purpose? Should we replace it by post-quantum-cryptography?
