„In my team, young scientists are exploring the photonic quantum technologies of the future in full breadth”

Prof. Dr. Christine Silberhorn,
Integrated Quantum Optics

We are a member of PhoQS

PhoQS offers us the opportunities to conduct interdisciplinary research with state-of-the-art infrastructure.



Our group develops and investigates novel optical devices and methods with regard to applications in quantum information processing, quantum communication and for the fundamental understanding of quantum theory. By using integrated optical devices in quantum optical experiments, the effort for the realisation of quantum light sources or converters can be greatly reduced on the one hand, and on the other hand, the implementation of quantum optical setups with a very high degree of complexity is possible for the first time. Both together represent an important milestone for the development of a quantum technology that, by using original quantum properties, enables novel applications that cannot be developed with classical resources.
