Canonical momenta in digitized Su(2) lattice gauge theory: definition and free theory

Abstract Hamiltonian simulations of quantum systems require a finite-dimensional representation of the operators acting on the Hilbert space $$\mathcal {H}$$ H . Here we give a prescription for gauge links and canonical momenta of an SU(2) gauge theory, such that the matrix representation of the for...
