Google Willow: QUOPS

216 QUOPS score

As stated in the source: “Q = 216 at 2.0x10^7 QUOPS/s (width 6)”

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Preprint (v1, 10 Sep 2026), not peer reviewed.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. Run dates not given.

Set-up
Physical qubits, width w=6, shape (6,216); capability-region run: 100 QUOPS circuits per shape, 1000 shots each; rate run: 25 QUOPS circuits at (6,216) with 500k shots each. Compiled with cirq (CNOT->CZ, PhasedXZ). Rate 2.0x10^7 QUOPS/s.
Method
QUOPS v1 (arXiv:2609.12146v1), physical-qubit architecture
