Quantinuum Helios: QUOPS
40 QUOPS score
As stated in the source: “Q = 40 at 4.9 QUOPS/s (width 4, [[7,1,3]] code)”
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Preprint (v1, 10 Sep 2026), not peer reviewed.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. Small logical demonstration (4 logical qubits); not comparable to physical-qubit scores without context.
- Set-up
- Helios-1. Logical qubits: [[7,1,3]] (Steane) colour-code encoding, width w=4 logical qubits, size 40; rate 4.9 QUOPS/s (main-text Table I; SI Sec. VII C, Table V).
- Method
- QUOPS v1 (arXiv:2609.12146v1), logical-qubit architecture ([[7,1,3]] code)
