Our research concerns photonic quantum technologies for a future quantum internet. We develop quantum light sources as well as spin-photon interfaces based on semiconductor quantum dots, emerging 2D materials, but also fluorescent proteins. Using the generated light states, we are implementing quantum information protocols in laboratory- and field-experiments, which can ultimately be scaled to large-scale quantum networks.

Our activities focus on the following aspects:

• Foundations of quantum technologies: generation and control of photonic- and spin-states
• Technological building blocks: quantum light sources, spin-photon interfaces, etc.
• Protocol implementations: quantum cryptography and networks in laboratory and field experiments
