I received my PhD in 2012 with the dissertation “Quantum Communication under Channel Uncertainty”. Afterwards I worked in the BMBF projects “System Models and Multipath Communication Protocols for Quantum Repeaters” and “Tap-proof Communication, Attacks and System Design” and was a DFG fellow at the Universitat Autònoma de Barcelona with Prof. Winter. I led a research transfer at TU Dresden from 2016 to 2018, before starting my position at TU Munich as head of the first DFG Emmy-Noether group in electrical engineering for the field of quantum technologies. In my group we develop theoretical quantum communication system designs with the goal of identifying quantum technology concepts that can be integrated into a next generation of communication networks. Among the highlights are an IEEE CITS best paper award for the concept “Entanglement-Enabled communication”, and the development of the quantum network simulator QuNetSim. Our tools are information-theoretic modeling and software engineering for quantum hardware.
