Estimation of sensitivity. a Noise in the switching probability as a function of the number of repetitions. The error bars (smaller than the symbol sizes) are standard errors obtained by the jackknife method. The solid line is the calculated \(1{\mathrm{/}}\sqrt {N_{{\mathrm{rep}}}}\) dependence. The arrow indicates the experimental data used to estimate the sensitivity. b Conversion from switching probability noise to frequency noise. The most sensitive working point is indicated by the magenta dashed line
