Rubidium Rydberg NQO project

This project explores nonlinear quantum optics in an ultracold gas of Rubidium atoms. The simple level structure of the alkalis and the established techniques for cooling and trapping Rb make this element a natural choice for exploring Rydberg EIT and nonlinear quantum optics. We first demonstrated the manipulation of the quantum statistics of light via Rydberg interaction in 2013 with this setup. Since then, we managed to implement a single-photon transistor, a single-photon absorber, and perform detailed studies of the Rydberg-mediated photon-photon interaction.
