Test of a time-bin entanglement-based QKD system in a commercial optical link. — •Oleg Nikiforov, Erik Fitzke, Daniel Hofmann, Kai Roth, and Thomas Walther — AG Laser und Quantenoptik, Institut für Angewandte Physik, Technische Universität Darmstadt, Schlossgartenstr. 7, 64289 Darmstadt, Germany

Quantum Key Distribution offers means for cryptographic key exchange, superior in security to the majority of contemporary classical key distribution schemes. We are working on a time-bin entanglement-based system for quantum key distribution. We test its performance in a real-world commercial telecommunication environment of Deutsche Telekom. In this contribution, we discuss the recent progress of our experiment and show first results.
