After many years of development of the basic tools, quantum simulation with ultracold atoms has now reached the level of maturity at which it can be used to investigate complex quantum processes. Planning of new experiments and upgrading of existing set-ups requires a broad overview of the available techniques, their specific advantages and limitations. This Technical Review aims to provide a comprehensive compendium of the state of the art. We discuss the basic principles, the available techniques and their current range of applications. Focusing on the simulation of various phenomena in solid-state physics through optical lattice experiments, we review their basics, the necessary techniques and the accessible physical parameters. We outline how to control and use interactions with external potentials and interactions between the atoms, and how to design new synthetic gauge fields and spin–orbit coupling. We discuss the latest progress in site-resolved techniques that use quantum gas microscopes, and describe the unique features of quantum simulation experiments with two-electron atomic species. Quantum simulation with ultracold atomic gases is an established platform for investigating complex quantum processes. Focusing on optical lattice experiments, this Technical Review overviews the available tools and their applications to the simulation of solid-state physics problems. Quantum simulation with ultracold atomic gases in optical lattices can be used to study condensed-matter quantum many-body systems, which are hard to simulate with conventional computers. The control of interatomic interactions is key to successful quantum simulation, and it can be implemented at short range and long range through various methods. Non-equilibrium phenomena can be studied by using controlled dissipation or lattice perturbations. Quantum gas microscopes currently offer the most precise tool for the manipulation and readout of optical lattice quantum simulators. The use of artificial gauge fields enables the simulation of charged particle physics; furthermore, non-trivial effects are accessible through use of spin–orbit coupling, topological lattices and synthetic dimensions. Going from alkaline-earth-metal to two-electron alkaline-earth-metal-like atoms allows the study of SU( N ) symmetrical systems.
