In our group we investigate Quantum Optics by exploring interactions between single photons and single atoms.
We achieve this by coupling single, laser-cooled Rb atoms to high-quality chip-based optical micro-resonators.
By confining light in such a small volume, the electric field of even a single photon is enhanced to a level that allows coherent interaction with a single atom.

Our group offers Ph.D. and M.Sc. tracks in both Physics and Chemistry.
