Abstract: Individually trapped neutral atoms provide a promising platform to engineer and probe quantum many-body systems in a controlled, bottom-up approach. They can be readily manipulated in large numbers and interact strongly when excited to Rydberg states. In the first part of this talk I will discuss the equilibrium and none-equilibrium properties of such atom arrays, which can host a plethora of different phases, depending on the atom arrangement. These include various conventionally ordered phases that break lattice symmetries, as well as topologically ordered phases such as spin liquids. I will discuss how these states can be prepared and probed. In the second part of my talk I will show how such systems could also be used to for implementations of quantum information processing protocols, ranging from quantum optimization algorithms for maximum independent set problems to digital approaches to quantum computing.
