General methods for digital quantum simulation of gauge theories
Henry Lamm, Scott Lawrence, Yukari Yamauchi · Physical review. D/Physical review. D. · 2019
A general scheme is presented for simulating gauge theories, with matter fields, on a digital quantum computer. A Trotterized time-evolution operator that respects gauge symmetry is constructed, and a procedure for obtaining time-separated, gauge-invariant correlators is detailed. We demonstrate the procedure on small lattices, including the simulation of a $2+1\mathrm{D}$ non-Abelian gauge theory.
