The plot (a) shows the minimum eigenvalues of the IM for the Markovian channel \(\Lambda _{t}^{(1)}\), it is clear that the experimental results are a good enough approximation of the zero eigenvalue. (b) Shows the minimum eigenvalues of the IM for the channel \(\Lambda _{t}^{(2)}\). The experimental results in this case are better than for the first channel as the standard deviation is small for all the points. (c) shows the minimum eigenvalues of the IM for the total non-Markovian channel \(\Lambda _{t}^{(T)}\), the points cover the theoretical curve, hence this channel is definitively non-Markovian by the CP divisibility criteria [29]
