Title

Time-Bin Photonic Qudits for Entanglement-Based Quantum Key Distribution Protocols

Abstract
We demonstrate the Bennett-Brassard-Mermin 1992 quantum key distribution protocol with time-bin entangled photonic qudits over a 60-km-long optical fiber link. The on-chip framework utilized therein addresses low effective qudit rates associated with time-bin encoding schemes.
