Quantinuum H2: QUOPS
1,320 QUOPS score
As stated in the source: “Q = 1320 at 353 QUOPS/s (width 12). With leakage postselection: 1320 at 360 QUOPS/s; 1392 at 231 QUOPS/s.”
Caveats
Preprint (v1, 10 Sep 2026), not peer reviewed. New benchmark defined and run by a team that includes the maker of two of the four machines (Quantinuum). Scores depend on compilation/routing effort chosen by each team. Rate methods differ by platform (reserved-window wall clock for Quantinuum; dedicated rate run with 500k shots for Willow; QPU usage time with batch approximation for ibm_boston), so rates are not strictly like-for-like.
- Set-up
- H2-1. Physical qubits, width w=12, passing shape (12,1320); 10 QUOPS circuits x 200 shots (2000 shots); timed run in reserved window, runtime 99 min 23 s (SI Table IV). Rate 353 QUOPS/s.
