Description
Simulating non-Abelian lattice gauge theories on quantum computers remains challenging, particularly in (3+1)-dimensions when using compact variables. The orbifold lattice formulation offers a universal and scalable framework for quantum simulation of SU(N) theories in arbitrary dimensions by using cartesian coordinates. Monte Carlo studies ($\href{https://arxiv.org/abs/2506.00755}{\mathrm{arXiv{:}2506.00755}}$ and $\href{https://arxiv.org/abs/2604.15132}{\mathrm{arXiv{:}2604.15132}}$) demonstrate the recovery of the Kogut-Susskind formulation for SU(2) and SU(3) in (2+1)-dimensions at large scalar mass. A linear counterterm reduces the scalar mass, and simplified Hamiltonians $H_1$ and $H_2$ lower quantum resource requirements while reproducing the same physics.
