      abstract     = {The solution of strongly-interacting quantum field theories
                      remains a major challenge in theoretical physics, often
                      requiring numerical solutions. A first-principles approach
                      in this direction is the lattice formulation, where
                      spacetime is approximated with a finite grid. In this work,
                      we examine the case of a compact pure-gauge U(1) lattice
                      gauge theory in (2 + 1) dimensions, presenting a strategy to
                      determine the running coupling of the theory and extracting
                      the non-perturbative Λ-parameter. This is achieved by
                      combining Monte Carlo simulations and quantum computing
                      techniques, matching the expectation value of the plaquette
                      operator. We also present results for the static potential
                      and static force, which can be related to the renormalized
                      coupling. The outlined procedure can be extended to other
                      Abelian and non-Abelian lattice gauge theories with matter
                      fields, and might provide a way towards studying lattice
                      quantum chromodynamics utilizing both quantum and classical
                      methods.},
