Benchmarking quantum gates using fixed-length sequences
The paper introduces a new randomized benchmarking protocol that uses fixed-length sequences of directly accessible gates, instead of relying on complex, compiler-optimized operations. This allows for fairer assessment of hardware performance. Key results quantify overestimation of fidelity by standard techniques. The method could enable building better noise models to advance error mitigation.
