Extended Data Fig. 7: The effect of post-processing on the lead shield effect A/B test.
From: Impact of ionizing radiation on superconducting qubit coherence
a, The upper row shows the P-value of the Wilcoxon signed rank test for three different test cases and for the different post-processing parameters. On the horizontal axis, the \({T}_{1}^{{\rm{cut}}-{\rm{off}}}\) is varied. The vertical axis shows the effect of applying a cut-off to the difference in the energy-relaxation rates when the shield status is changed. The first column shows the actual data. The middle column shows a reference experiment, in which the energy-relaxation rates are compared without moving the shield. The last column shows the data when the energy-relaxation rate pairs are randomized. The lower row shows the median of the effect of the shield on the energy-relaxation rate δΓ1. b, The median of δΓ1 along the dashed lines in a. The shaded area shows 68% CIs for the median.
