Scatter Plot from Scientific Research

Two-qubit gate fidelities extracted from different error characterization measurements of IRB, and GST. The fidelity of the FBT analysis from certain IRB is the neighbouring data point. This data are also presented in Extended Data Table 3 . The error bars are the errors of the fit. The average and the standard deviation of the IRB measurements are indicated with lines and shaded areas around the line. Each IRB run consists of 200 (A) or 500 (B and C) circuit randomizations with 100 single shots for each run. Inset: DCZ fidelity as a function of lab time, where the transient fidelities are extracted from FBT analysis on IRB experiment data. The error bars in the main gfigure and the shaded region in the inset indicate the 95% confidence interval of the fidelity based on the error coming from the fit.
