The possibility to trap atoms in well-controlled engineered environments in optical lattices has proved to be a powerful tool for quantum-simulation of strongly correlated quantum systems. The great challenge to obtain full single-site resolution and single-atom control in optical lattices was overcome by the development of quantum-gas microscopes  and I will present an overview of the recent developments in this field . Fluorescence imaging of atoms has made it possible to directly observe bosonic and fermionic many-body quantum systems with single-atom resolution in an unprecedented way, giving access to, e.g., in-situ measurements of temperature and entropy distributions, direct observation of correlations and their spreading, or the build-up of entanglement. I will also present how we achieved single-atom-resolved fluorescence imaging of fermionic potassium-40 atoms using electromagnetically-induced-transparency (EIT) cooling , and a new way of Raman gray-molasses cooling on the D2-line , and report on our progress towards the study of strongly correlated fermionic quantum systems and their out-of-equilibrium dynamics.
