Experimental Quantum Physics

Welcome to the Experimental Quantum Physics group at the University of Bonn.

Our research is concerned with the investigation of ultracold Atoms and trapped ions for the purpose of quantum information processing and quantum simulation. A brief video with an introduction to our research: click here.

We offer experimental projects for Bachelor-, Master- and PhD theses.

If you are interested please contact Michael Köhl.
