Figure 3From: Simulating \(Z_{2}\) lattice gauge theory with the variational quantum thermalizerDepiction of a single-layer of a variational quantum circuit in the gauge-redundant formulation. The layer is composed of one sublayer of single-qubit rotation gates and a sublayer containing the decomposed three-qubit gate which is formed from the gauge-matter term in the gauge-redundant formulation. All relevant gates contain variational parameters \(\Delta _{i}\)Back to article page
