Rydberg-dressing allows for the introduction of controllable long-range interactions for ground state atoms. In this work, we realize a Rydberg-dressed Ising spin system and study the interaction induced growth of spin-spin correlations in an interferometric measurement. This enables us to benchmark the predicted tunability of Rydberg-dressed interactions.

Cold atomic gases resonantly excited to Rydberg states can exhibit strong optical nonlinearity at the single photon level. We observe that in such samples radiation trapping leads to an additional mechanism for Rydberg excitation.

Highly-excited Rydberg atoms have strong long-range interactions resulting in exotic optical properties such as large single photon non-linearities and intrinsic bistability. In this paper we study optical-driven non-equilibrium phase transitions in a thermal Rydberg gas with a sensitivity two order of magnitude higher than in previous work.

By mapping the strong interaction between Rydberg excitations in ultra-cold atomic ensembles onto single photons via electromagnetically induced transparency, it is now possible to realize a medium which exhibits a strong optical nonlinearity at the level of individual photons. We review the theoretical concepts and the experimental state-of-the-art of this exciting new field, and discuss first applications in the field of all-optical quantum information processing.
