Description
Hamiltonian lattice gauge theories provide access to important physics that remains difficult to study using conventional Euclidean methods. Quantum computers are naturally suited to implementing such formulations. With near-term quantum hardware in mind, we present an efficient framework for incorporating fermionic matter into 3+1-dimensional lattice gauge theories. The key idea is to combine trivalent lattice geometries with staggered fermions, reducing the local Hilbert-space dimension while preserving gauge invariance and the essential physics of the underlying theory. This construction offers a scalable route toward quantum simulations of non-Abelian gauge theories with fermions in 3+1 dimensions.
