Coincidence Detection based Quantum Key Distribution Protocol (QTu8B.17)

Presenter: Anindya Banerji, Physical Research Laboratory

We exploit inherent randomness in photon number distribution of weak coherent pulses coupled with coincidence detection to perform quantum key distribution. This results in higher key rate over longer distance compared to decoy state protocol.
