Our group explores how individual Rydberg atoms and the strong interaction between them can be used to probe and manipulate other quantum systems, for example few-photon states of optical fields. The rich level structure of Rydberg atoms allows coupling to other systems over a wide frequency range from RF to the optical domain. At the same time, the Rydberg-blockade mechanism based in the strong Rydberg-Rydberg interaction provide an extreme nonlinearity which can ultimately enable control over the coupled systems on the level of single quanta.

Rydberg EIT project

This project explores how the interaction between Rydberg atoms can be mapped on individual optical photons. Ultimately, our goal is to realize a nonlinear optical medium that enables full control over the quantum state of single and few photon light pulses.
