H2 56 qubits, depth 16, 2^44 elements (56 qubits, 448 two-qubit gates) . Fewer multiplications rank first. Equal counts are ranked by submission number (lower first). Each participant appears once, with their best accepted submission.
Scores are public; a participant can keep the file itself private.
