Fig. 8: Energy and entropy distributions.
From: Experimental characterization of the energetics of quantum logic gates

Comparison between the experimental distributions of ΔE (a, b) and Δσ (c, d), evaluated at ωLt = 0.31 and 0.62. It is worth noting that in such (rescaled) time instants, the first statistical moments (i.e., the average) of the energy change and the entropy, respectively, take their maximum values.
