Quantum Computing Report Card Reveals 100,000x Gap to Useful Computation

Quantum computing has received its first comprehensive report card, developed by a team led by Sandia National Laboratories. The new benchmark, called QUOPS (Quantum Universal Operations Performance System), evaluates full system performance across various hardware types and reports two summary metrics: Q and Ω.

The results of the QUOPS benchmark, released on September 10, 2026, show that Quantinuum's Helios-1 trapped-ion processor achieves a Q score of 1,504. This is roughly seven times larger than Google's superconducting Willow (Q = 216) and IBM's ibm_boston (Q = 204). However, all three systems are still far from practical use, with a gap of around 100,000 times.

QUOPS addresses the limitations of prior benchmarks by evaluating full system performance, including compilation, error correction, syndrome decoding, and error mitigation. The benchmark captures the integrated effect of these processes, providing a more comprehensive view of a machine's capability. Unlike previous metrics, QUOPS evaluates circuits of varying shapes, not just square ones.

The results show that Helios-1's Q score declines relatively little as circuit width increases, thanks to its Quantinuum's Quantum Charge-Coupled Device (QCCD) design. In contrast, Google's 2D-grid superconducting design can only entangle physically adjacent qubits, increasing circuit depth and error accumulation.

The QUOPS framework is designed to grow with the field and has already been applied to a fully fault-tolerant logical architecture on Helios-1. The results show that current error-correction codes impose significant overhead, but the benchmark provides a baseline from which progress can be tracked across successive hardware generations.
