Group Seminar MPQ: Rydberg atoms served hot and cold

The coherent control of mesoscopic ensembles of atoms by the Rydberg blockade are the basis for proposed quantum devices as integrated quantum gates and single photon sources. So far, experimental progress has been limited to complex experimental setups that use ultracold atoms. We have been able to gain some insight on the time evolution of strongly interacting Rydberg gases of evaporativly cooled Rubidium atoms. In a new project we try to employ this knowledge to implement Rydberg excitations in microscopic vapor cells and I will present our results on coherent Rabis-oscillations to a Rydberg state at room temperature.
