Description: Anthropic gave Claude Mythos 5 plain-language specs for 8 quantum circuits plus an automated scorer. In 7 of 8 tasks its designs cut both Toffoli gates and qubits vs the state of the art; one elliptic-curve design from a 53-hour run uses 17× fewer gates (12% more qubits), and a decoder got 12× fewer gates vs Google's previous design. Caveat: checked by a classical evaluator.
