On July 3rd, 2009, the Excellence Cluster “Frontiers in Quantum Photon Science” has been founded as new and highly profiled research activity within the framework of the excellence initiative of the federal state of Hamburg.

The Cluster combines the expertise from laser-physics, quantum optics, short-time- and X-ray-physics as well as condensed matter physics. It thus brings together the photon science activities from the University, DESY and the Max-Planck research groups at Hamburg University in terms of research and education.
