Fig. 3: Statistical moments of ΔE.
From: Experimental characterization of the energetics of quantum logic gates
a Statistical moments of the energy probability distribution as a function of time. We compare the experimental values and the corresponding theoretical predictions. The initial state of the two-qubit system is the density matrix ρ0 in Eq. (9). We show the experimental (theoretical) values of the moments from 1st to 5th as black, red, green, blue, and magenta dots (lines) for the same parameters as in Fig. 2. b Absolute error \(| {\langle \Delta {E}^{h}\rangle }_{{\rm{theo}}}-{\langle \Delta {E}^{h}\rangle }_{\exp }|\) accounting for the difference between theoretical and experimental statistical moments of ΔE from 1st to 5th, provided by black circles, red dots, green diamonds, blue crosses, and magenta squares, respectively.
