Scalable fast benchmarking for individual quantum gates with local twirling Editors' Pick
Fig. 1. Illustrations of circuit and procedures used in (a) CCB and (b) CAB protocols. The orange boxes represent the target gate
Fig. 2. Illustrations of the noisy CCB circuit with local gauge transformation. For simplicity, we show the case that the local gates are noiseless. The grey dashed boxes denote the noise channel

Fig. 4. Simulation results for the five-qubit quantum error correcting encoding circuit with a noise channel composed of a depolarizing channel
Fig. 5. Illustrations of the CCB circuit with local gauge transformation. Circuit (a) is equivalent to the original CCB circuit in the main text if all of gates are ideal. The orange boxes represent the target gate
Fig. 7. Simulation results of CAB and ICRB for benchmarking a CZ gate. (a) The error bar of the fidelity obtained from 50 experiments via CAB and ICRB protocols. The
