(a) Average produced heat as function of protocol time τp, for the three different sets of inputs (that is, ‘01’, ‘10’ and ‘11’). With increasing protocol time the produced heat decreases following a power law. (b) Heat distribution P(Q) for the case τp=9 ms, input ‘11’. Red bars represent the histogram of the measured distribution, black line represents the fit with a Gaussian distribution, and black dashed line the average value of produced heat. It is interesting to note that, although <Q>>0, the distribution of the generated heat has negative tails. (c) Mean produced heat normalized over the square of maximum displacement of the cantilever tip as a function of the protocol time τp. The produced heat is evaluated for all combinations of the input for different values of voltages applied to the input probes. For equal protocol time, τp, all points show approximately the same value in agreement with the dissipation model presented. Solid line represents the fit with the dissipation model.
