The quantum simulation model \(\pmb{\{H_{1}^{\mathrm{open}}, S_{z}\}}\) evaluated for \(\pmb{n=10}\) spins. (a) Eigenvalues of the FIM at low temperature \(\beta=10\). The ten largest eigenvalues are shown in red, whereas the others are shown in gray. (b) The elements of the eigenvector associated to the largest eigenvalue, which specify the composite influential parameter deviation.
