Simulating lattice gauge theories on quantum computers poses significant challenges, motivating new theoretical frameworks. The orbifold lattice formulation provides a scalable approach for SU(N) theories in any dimension. Monte Carlo simulations (arXiv:2604.15132) show that for SU(2) in (2+1) dimensions, it recovers the Kogut-Susskind formulation in the large scalar mass limit. To reduce the need of large scalar mass, two strategies were employed: adding a linear counter-term to the Hamiltonian and tuning the effective lattice spacing.
