The research program of the QO group has three leading themes: Optical Physics, Quantum Optics, and Photon-Matter Interactions. We work mostly at the boundaries between these themes with entanglement as a bridging and binding agent. Schematically, our themes are sketched in the figure below. Our research focus has steadily moved upwards.

More details can be found in the overview of our current "research projects", where you will also find a description of the righthand figure.
