Michael Kues is University Professor of Photonic Quantum Technologies at the Institute of Photonics, Leibniz University Hannover, where his group develops scalable photonic quantum systems using fiber and integrated-optics platforms. His research spans quantum frequency-comb sources, frequency-bin encoding, and methods that allow quantum signals to coexist with conventional data in optical-fiber networks—key steps toward practical quantum communications. He is also part of the PhoenixD Cluster of Excellence in Hannover.
