Beschreibung

Interfacing light and matter at the quantum level is at the heart of modern atomic and optical physics and enables new quantum technologies involving the manipulation of single photons and atoms. A prototypical atom-light interface is electromagnetically induced transparency, in which quantum interference gives rise to hybrid states of photons and atoms called dark-state polaritons. Strong long-range interactions between Rydberg atoms give rise to an effective interaction blockade for dark-state polaritons, which results in large optical nonlinearities, modified polariton number statistics and the emergence of non-classical light fields. My talk will give an overview over recent developments in this rapidly evolving field of research with special emphasis on our recent experiments on the statistical properties of the dark-state polaritons [1] and on an all-optical method to in-situ image Rydberg atoms embedded in dense atomic gases [2]. * Work done in collaboration with Vladislav Gavryusev, Georg Günter, Stephan Helmrich, Christoph S.
