The plot (a) shows the minimum eigenvalues of the IM for the non-Markovian channel \(\Lambda _{t}^{(1)}\), it is clear that the experimental results are in agreement with the theoretical minimum eigenvalues of the IM. (b) Shows the minimum eigenvalues of the IM for the channel \(\Lambda _{t}^{(2)}\), the experimental results in this case deviate from the theoretical curve but this channel is still non-Markovian by CP divisibility. (c) shows the minimum eigenvalues of the IM for the total Markovian channel \(\Lambda _{t}^{(T)}\), the points cover the theoretical curve and the initial points, although negative, are still a good enough approximation of zero, this is a problem face when the minimum eigenvalue is zero. Hence, this channel is Markovian by the CP divisibility criteria [29]
