Study of Rydberg-surface interactions in thermal atomic vapor — •Ralf Ritter, Daniel Barredo, Robert Löw, and Tilman Pfau — 5. Physikalisches Institut, Universität Stuttgart, 70569 Stuttgart, Germany

The coherent control of strong interactions between Rydberg atoms hold great promise for the manipulation of quantum information. In ultracold experiments several results have already been achieved to proof the basic concepts for this intention. However, thermal atomic vapor cells offer an attractive alternative in terms of scalability for practical devices [1]. For the successful applicability of this approach, decoherence effects with nearby walls need to be investigated and minimized.

In our work, we study the Rydberg atom-surface interaction in a UHV environment as a function of surface composition, corrugation, and temperature for different Rydberg states, atomic species and buffer gases. We will present the versatile setup we utilize for this project and discuss the current status of the experiment.
