The data are well described by a cubic polynomial fit of the form ax2 + bx + c, with the determination coefficient of R2 = 0.9800. The fitted coefficients (95% confidence intervals) are: a = 0.0882, b = 0.00940, and c = − 0.0201. The left and right insets display representative fits of the dephasing-induced population decay measured at white noise amplitudes of 3.5 V. Each data point is obtained by averaging over 200 experimental repetitions with error bars indicating standard deviation.
