Welcome to the website of the Quantum Theory Group of Prof Dr Christopher Gies

The research of our group focuses on enabling new quantum technologies, including quantum machine learning at the interface of analogue and quantum computing, protocol simulations for quantum repeaters, quantum light sources, and multipartite entanglement generation and classification. The underlying systems and hardware platforms are usually based on solid-state technologies. Our focus is on the theoretical modelling of semiconductor nanostructures at the interface of solid-state physics, quantum optics and quantum information. We use many-body methods to understand and predict physical phenomena based on the underlying microscopic processes and correlations.

A further component of our research work lies in the optical and quantum optical properties of atomically thin semiconductors, the so-called van der Waals materials. We are particularly interested in their potential for optoelectronic applications in the field of cavity quantum electrodynamics.

We work closely with experimental partners as part of several cooperative research projects. Through joint efforts, new phenomena can be uncovered and understood, especially when they result from correlations and many-body effects in semiconductors.
