Two-dimensional ${\mathbb{Z}}_2$ lattice gauge theory on a near-term quantum simulator: variational quantum optimization, confinement, and topological order

Luca Lumia, Pietro Torta, Glen B. Mbeng +4

We propose an implementation of a two-dimensional ${\mathbb{Z}}_2$ lattice gauge theory model on a shallow quantum circuit, involving a number of single and two-qubits gates comparab…
