CRQC (plural CRQCs)

(cryptography) Initialism of cryptographically relevant quantum computer; a quantum computer powerful enough to break modern cryptography (e.g., using Shor's algorithm to break RSA or Ed25519).

  It's almost like the NSA is dropping a not-so-subtle hint, though why it would is debatable. If it has a CRQC, or is on the path to one, it might want to warn allies, vendors, and citizens to think about using quantum-resistant technologies in case bad people develop a CRQC too. But why would the spies tip their hand so? It's all very curious.
