Figure 1
Log-log plot of the residual energy of the system at \({t}_{f}=14\) as a function of the variance D and of the times at which the measurements are performed: \({t}_{1}=\tau \) and \({t}_{2}=2\tau \). We observe that the residual energy decreases eventually going to \(5.49\cdot {10}^{-4}\) which is the residual energy of the system in the absence of measurements for this choice of tf (red dashed line at the bottom). The inset in the right top corner shows a sketch of the system-ancilla ensemble.
