In this talk\, I will discuss recent progress towards q uantum simulation of gauge theories. A particular focus will lie on a cent ral issue in this context: How to ensure that the quantum simulator fulfil ls the local symmetry that defines the gauge theory? In other words\, how can one ensure that the ultracold atoms or superconducting qubits in a qua ntum simulator behave as electrons\, positrons\, and electric field\, and mimic Gauss’s law of electrodynamics? I will present our theoretical eff ort to quantify – and mitigate – the influence of microscopic violatio ns of gauge symmetry [1] as well as the first quantum simulation experimen t that measured the fulfillment of Gauss’s law [2]. Through these discus sions\, I will aim at outlining a roadmap towards mature and practically r elevant quantum simulation of gauge theories.\n[1] Jad C.
