(Left) Comparison of the classically simulated Trotterized expectation value of the mesonic observables \(\hat{J}_{1/2}\) for Trotter step size \(\delta t = 0.4\) (diamonds) and the exact results (dashed lines).(Right) The wave function overlap \(|\langle{\psi _{0}}|{\psi (t)}\rangle |^{2}\) for several values of the baryon chemical potential \(a\mu _{B}\) for Trotter step size \(\delta t = 0.2\). We used a system of linear extent \(L = 4\) and periodic boundary conditions for the initial state \(|{\psi _{0}}\rangle = (|{+}\rangle |{0}\rangle |{+}\rangle )^{\otimes L}\)
