The evolution of \(F_Q\) and \(F_C\) as a function of time when \((h_0/J,h_1/J)=(0.191,0.161)\) are tuned to be on the line of the vanishing Floquet gap for: (a) \(\alpha \rightarrow \infty\); and (b) \(\alpha =3\). The variance Var(\(h_1\)) in the estimation of \(h_1\) using Bayesian inference for two different numbers of repetitions M for: (c) \(\alpha \rightarrow \infty\); and (d) \(\alpha =3\). The other parameters are \(N=13\), \(J\tau =0.2\), and \(L=4\).
