Figure 12From: Digital simulation of convex mixtures of Markovian and non-Markovian single qubit Pauli channels on NISQ devicesThe process fidelities for the χ matrices of the implemented channels after MLE for times from 0 to 8.9 seconds with time step 0.1 seconds. (a) and (b) show the fidelities for the non-Markovian channels \(\Lambda _{t}^{(1)}\) and \(\Lambda _{t}^{(2)}\) respectively, the fidelities for these channels are good as for \(\Lambda _{t}^{(1)}\) the fidelity is 1 for a large part of the time interval, for \(\Lambda _{t}^{(2)}\) the fidelities do fluctuate but are also very good. (c) shows the fidelity for the total Markovian channel \(\Lambda _{t}^{(T)}\)Back to article page
