Rydberg-dressed atoms are a promising platform for performing quantum simulations of spin Hamiltonians. They allow for controllable long-range interactions which can give rise to both Ising and Heisenberg Hamiltonians. We are constructing an experiment optimized to simulate frustrated systems using a 2-D lattice of cesium atoms. The spins will be represented by two hyperfine ground states with long-range interactions achieved by a weak off-resonant coupling to a Rydberg state. Our experiment is designed for state-sensitive imaging with single site resolution to enable full characterization of the many-body system. We will apply this system initially to disordered quantum magnets and ultimately to frustrated models in triangular, honeycomb, and Kagome lattices.
