The Cold and Controlled Molecules and Ions Group at the University of Basel (Switzerland), headed by Prof. Stefan Willitsch, specialises in the preparation and control of cold molecules and molecular ions and their applications. The research of the group is highly interdisciplinary, situated at the interface between quantum optics, quantum physics, chemistry and the nanosciences.

We are developing a microwave ion trap capable of confining ultra-cold plasmas. The main long-term objective is to cool the electrons so much that they de-localise over several ions in a Coulomb crystal stored in a Paul trap. Such a quantum-mechanical system shall be used as quantum gates in the future. Still, we are mainly interested in interactions of the quasi-free electrons with the external electro/magnetic fields.
Our group explores quantum fluids of light to study emergent many-body phenomena, such as superfluidity or turbulence. Quantum fluids of light can be experimentally realized within microscopic optical cavities, where the photons are trapped in intricate lattice or box potentials. With this experimental platform, we investigate novel topological physics, the interplay of quantum effects and dissipation, and quantum communication.
