Advancing Quantum Simulation in Lattice Gauge Theories and High-Energy Physics

Lattice gauge theories, stemming from Quantum Chromodynamics (QCD) in particle physics, catalyze the evolution of quantum information technologies. Beyond the ambitious goal of simulating complex QCD aspects, these theories offer valuable insights into condensed matter physics and quantum information science. We will explore recent developments in quantum science approaches applied to lattice gauge theories, encompassing both classical tensor network methods and quantum hardware implementations. The former is exemplified through studies on Abelian and non-Abelian lattice gauge theories, while the latter discusses proposals for quantum simulators employing diverse platforms such as trapped ions, Rydberg atoms, and superconducting circuits. We culminate in a review of the first experimental quantum simulations of the Schwinger model using trapped ions.
