DESCRIPTION:Speaker: Sebastian Hofferberth\nhosted by Julian Léonard\nAb
 stract: Mapping the strong interaction between Rydberg excitations in ultr
 acold atomic ensembles onto single photons enables the realization of opti
 cal nonlinearities which can modify light on the level of individual photo
 ns. This novel approach forms the basis of a growing Rydberg quantum optic
 s toolbox\, which enables photonic logic building-blocks such as single-ph
 oton sources\, all-optical transistors and photonic quantum gates. More br
 oadly\, interacting photons are a novel approach to realize strongly corre
 lated quantum few-body systems.In this talk\, I will introduce the general
  concepts of Rydberg quantum optics and present recent experiments from ou
 r labs utilizing both Rubidium and Ytterbium atoms as nonlinear medium. Sp
 ecifically\, I will show recent results on transverse photon-photon intera
 ction enabling photon-number dependent beam-shaping. Furthermore\, I will 
 present our first investigations of Rydberg-mediated photon-interaction in
  Ytterbium\, highlighting possible advantages of this new platform.
