Quantum Optics and Quantum Information

Quantum Optics and Quantum Information Research
Department leader

We deal with the fundamental problems of quantum theory, i.e., the measurement theory and the so-called mesoscopic systems which lie on the border of the microscopic quantum and the macroscopic classical world. Our scientific objective is to extend the high-precision control achieved in the manipulation of individual atoms, trapped ions, photons and ultracold quantum gases to composite quantum systems, such as larger molecules or hybrid — optical and condensed matter based — systems, and to networks of elementary quantum objects. All of our research projects are related to specific physical systems, and are carried out in close collaboration with experimental groups.

Cavity quantum electrodynamics and ultracold atoms
The group deals with elementary quantum systems, larger networks constructed of such systems, and their applications in quantum information processing as well as the description of their specific physical realisation...
