Fig. 6. The learned Pauli noise model using intercept CB.

The feasible region (blue bars) are taken from Fig. 4. Estimates of Pauli fidelities (a) and Pauli error rates (b). Each data point is fitted using seven different circuit depths L = [2, 2², . . . , 2⁷]. For each depth C = 150 random circuits and 2000 shots of measurements are used. Data are collected from ibmq_montreal on 2022-03-23.
