Figure 7From: Simulating \(Z_{2}\) lattice gauge theory with the variational quantum thermalizer(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 \(T/m\) for \(\mu = 0\) on a system with \(N=8\) matter sites, corresponding to \(n_{q} = 7\) qubits in the resource-efficient formulation.
