Fig. 5: Measurement of efficiency fluctuations.

a, b Histograms of the experimentally measured efficiency η = –βW/I for τ = 3 ms and N/S = 0.06 (orange), 0.32 (olive) and 0.79 (wine in inset of b). The solid curves are guides to the eyes. The violet (red) bars correspond to βW < 0(βW > 0) and I > 0(I < 0), respectively. c Efficiency distribution (from simulation) for N/S = 0.034 at four different cycle times τ = 0.1 (orange), 1 (olive), 3 (blue), and 10 (red) ms. d Contour plot showing the fluctuations in efficiency distribution as a function of noise level N/S for τ = 3 ms.
