Description
We study the ground state energy of a two-dimensional pure $\mathbb{Z}_2$ lattice gauge theory (LGT) on a triangular lattice by applying the sample-based quantum Krylov diagonalization. Moreover, an error detection and mitigation method based on Gauss’s law constraints is incorporated. We demonstrate this method in the $\mathbb{Z}_2$ LGT using the IBM quantum hardware and classical tensor network simulation, and investigate the errors arising from the algorithm and hardware noise.
