(Left) The fidelity of the approximation to the Gibbs state produced by VQT on the classical simulator (\(n_{s} = 10^{4}\)) and ΔF as a function of \(T/m\) at \(\mu =0\) on a system with \(N=4\) matter sites, corresponding to \(n_{q} = 7\) qubits in the gauge-redundant formulation. (Right) The chiral condensate \(\langle \bar{\psi}\psi \rangle \) calculated on the same data sets where for clarity the exact result has also been included
