In our research we aim at developing quantum technology for single-photons on silicon chips. We design, fabricate and test photonic devices using advanced nanotechnology that allows for straightforward replication of functional units. Our activities focus on three core constituents of chip-scale quantum optics:- Design of efficient interfaces between optical waveguides and single-photon sources.
- Development of nanophotonic devices and quantum circuit components.
- Integration of superconducting nanowire single-photon detectors with nanophotonic waveguides.
Combining all three of these research directions leads to scalable quantum information processing with tremendous benefits over classical computation and communication systems.AG Prof. Dr. Heindel – Photonic Quantum Networks
© Tobias Heindel 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

AG Prof. Dr. Kleinmann – Foundations of Quantum Theory
© Kleinmann We investigate the theoretical foundations of quantum theory, with a particular focus on the structure of quantum theory as an operational physical theory. The aim of our research is to formulate the principles of quantum mechanics precisely and improve our understanding of them, thereby enabling new experimental tests as well as applications in quantum technologies. Our work focuses in particular on the following topics:
- Features of quantum dynamics and quantum processes
- Correlations and axiomatization of composite quantum systems
- Quantum measurements as a physical process
- Application of concepts from quantum information theory to new physical contexts
- Characterization of technological and fundamental quantum systems

Quantum technologies rely on the ability to distribute, process, and protect information in the presence of noise, imperfections, and limited resources. In the Theoretical Quantum Communication Group, we develop the theoretical foundations and practical concepts required for future quantum communication systems, with a particular focus on quantum networks, quantum error correction, and quantum cryptography.
A central theme of our work is the design and characterization of complex quantum resources—from multipartite entanglement, graph states and higher-dimensional quantum systems (qudits) to error-correcting structures and network architectures—that enable quantum communication, computation, and security beyond the capabilities of classical technologies. Our research is carried out in close collaboration with experimental groups and industrial partners in quantum photonics, communication, and quantum technologies.
