Fig. 5

Statistical distributions of the relative deviation from the linear behaviour in (14) of the numerically obtained infidelity gradients cd for Ng = 5000 gates for γt [10−5, 10−3], as a function of the dimension d3, 8. The candlestick bar chart should be interpreted as indicated in the upper right, with σ denoting the standard deviation, and the error bars denoting the extremal values. The lower right inset shows the same results for d2, 4.
