Rydberg systems offer exciting prospects for future all optical quantum computing due to the large scaling and also for investigation of exotic many-body quantum states of light. Mapping the strong interaction between Rydberg excitations in ultracold atomic ensembles onto single photons paves the way to realize and control high optical nonlinearities at the level of single photons. In our group, we explore this novel approach in multiple experimental setups.

Here we present the progress with our new Rydberg quantum optics experiment utilizing ultracold Ytterbium as optical medium. The specific goal of this new setup is to study the interactions between a large number of Rydberg polaritons simultaneously propagating through a medium with extremely high atomic density. Towards this goal, Yb offers several advantages compared to alkali atoms; such as long coherence times, long Rayleigh length, simple energy level scheme and efficient cooling transitions. We discuss details of our experimental setup and report on the progress towards observation of few-photon nonlinearities in Yb.
