**Simulating lattice gauge theories within quantum technologies**

Lattice gauge theories, which originated from particle physics in the context
of Quantum Chromodynamics (QCD), provide an important intellectual stimulus to
further develop quantum information technologies. While one longterm goal is
the reliable quantum simulation of currently intractable aspects of QCD
itself, lattice gauge theories also play an important role in condensed matter
physics and in quantum information science. In this way, lattice gauge
theories provide both motivation and a framework for interdisciplinary
research towards the development of special purpose digital and analog quantum
simulators, and ultimately of scalable universal quantum computers. We will
review recent results and new tools from a quantum science approach to study
lattice gauge theories. Two new complementary approaches are discussed: first,
we will present tensor network methods – a classical simulation approach –
applied to the study of lattice gauge theories together with some results on
Abelian and nonAbelian lattice gauge theories. Then, we will report on recent
proposals for the implementation of lattice gauge theory quantum simulators in
different quantum hardware, e.g., trapped ions, Rydberg atoms, and
superconducting circuits. Finally, we will review the first proofofprinciple
trapped ions experimental quantum simulations of the Schwinger model.
