A gauge redundancy-free formulation of compact QED with dynamical matter for quantum and classical computations
Julian Bender, Erez Zohar
We introduce a way to express compact quantum electrodynamics with dynamical matter on two- and three-dimensional spatial lattices in a gauge redundancy-free manner while preservin…

Real-time dynamics in 2+1d compact QED using complex periodic Gaussian states
Julian Bender, Patrick Emonts, Erez Zohar +1
We introduce a class of variational states to study ground state properties and real-time dynamics in (2+1)-dimensional compact QED. These are based on complex Gaussian states whic…

Digital quantum simulation of lattice gauge theories in three spatial dimensions
Julian Bender, Erez Zohar, Alessandro Farace +1
In the present work, we propose a scheme for digital formulation of lattice gauge theories with dynamical fermions in 3+1 dimensions. All interactions are obtained as a stroboscopi…
