P4 – Quantum Key Hubs

The security of Quantum Key Distribution (QKD) is based on laws of nature. The overall goal of this project is to develop a photon-based QKD structure in a star like topology and to comprehensively explore its fundamental quantum features. The individual goals are to implement wavelength-division multiplexing in a QKD structure including a field test in a real telecom network, to determine the multipartite statistical correlations of the realized QKD structure, and to investigate the scalability of the QKD structure beyond four parties.
