Complete randomized benchmarking protocol accounting for leakage errors
Complete randomized benchmarking protocol accounting for leakage errors
Randomized Benchmarking allows to efficiently and scalably characterize the average error of an unitary 2-design such as the Clifford group $\mathcal{C}$ on a physical candidate for quantum computation, as long as there are no non-computational leakage levels in the system. We investigate the effect of leakage errors on Randomized Benchmarking …
