In this talk, I will present our recent studies of quantum magnetism using a Rydberg quantum simulator. I will first explain how, using two different Rydberg levels such as nS and nP, we can study the equilibrium properties and the dynamics of dipolar XY magnets, in one [1] and two dimensions [2,3]. I will then show that by using three Rydberg states, nS, nP, and n’S, one can realize a bosonic version of the t-J model that describes doped magnet [4].
