Quantum computing is an industry building devices and services that use quantum effects for computation.
Post-quantum cryptography (PQC) is the migration of everyday encryption to algorithms meant to resist future cryptanalytic attacks, including attacks that might someday use quantum hardware.
Headlines often blend the two because both use the word quantum. Items tagged pqc are about crypto migration, standards, or regulation, not about qubit counts or lab results unless the story explicitly ties them together.
