Quantum Simulation of Quantum Link Model on Ladder Geometry — •Sabhyata Gupta, Younes Javanmard, Luis Santos, and Tobias Osborne — Institut für Theoretische Physik - Leibniz Universität Hannover

Lattice Gauge Theory (LGT) stands as a cornerstone in the edifice of theoretical physics. LGTs, however, present a formidable computational challenge due to their intricate nature, requiring substantial computational resources. This work underscores the profound potential of quantum simulation as a transformative tool within the domain of lattice gauge theory. Using physical constraints on the Hilbert space enforced by Gauss law in U(1) (2+1)-d LGT, we formulate the problem efficiently to study its dynamics on a NISQ device. We employ state of the art techniques like fast-forwarding, and scaled quantum gates to achieve longer simulation of a large system.
