Aarhus University Seal / Aarhus Universitets segl


The Center for Complex Quantum Systems (CCQ) is a Center of Excellence funded by the Danish National Research Foundation that was initiated in September 2020. The aim of the center is to advance our understanding of collective quantum phenomena in large collections of particles, such as atoms, ions and photons. We seek to exploit these insights to generate and control emergent interactions that may arise at the interface of such distinct quantum system, and to develop new techniques for the probing and steering of complex quantum dynamics.

The center brings together three theory groups (Thomas Pohl, Georg Bruun and Klaus Mølmer) and two experimental groups (Jan Arlt and Michael Drewsen) who contribute complementary expertise in atomic physics, quantum optics, many-body theory and quantum information science. In the center, we collaborate and interact closely with several groups at Aarhus University and our international partners at Durham University, the University of Innsbruck, the ETH Zurich, the Weizmann Institute of Science and the Institute for Theoretical Atomic, Molecular, and Optical Physics at the Harvard-Smithsonian CfA.
