Quantum Simulators provide new levels of understanding of equilibrium and out-of-equilibrium properties of many-body quantum systems -- one of the most challenging problems in physics. Rydberg atoms, due to their outstanding versatility, hold a potential to perform a great variety of useful quantum simulations. Exploiting different aspects of the same experimental and theoretical tools, a whole family of Rydberg Quantum Simulators can address both the coherent and incoherent dissipative dynamics of many-body quantum systems, with potential applications in the understanding and design of artificial light harvesting systems, large quantum systems with controlled decoherence, and novel materials. This workshop will discuss the latest development in the Rydberg atom physics and quantum simulators, focusing on novel generic approaches to quantum simulation, where Rydberg atoms will allow both digital (gate) and analog (interaction) simulations.
