| Quantum key distribution with a bright source of telecom single photons based on quantum frequency conversion | QCRYPT 2021 | Christopher L. Morrison, Francesco Graffitti, Zhe Xian Koong, Nick G. Stoltz, Roberto G. Pousa, Dirk Bouwmeester, Luca Mazzarella, John Jeffers, Daniel K.L. Oi, Alessandro Fedrizzi |
We demonstrate fibre-based quantum key distribution over 175 km using a bright frequency converted quantum dot single-photon source. The source is capable of producing count rates approaching 2 MHz at 1550 nm with second order correlations on the order of 3%. This allows for a measured key rate of 130 bps (100 kbps) at 175 km (50 km) in the asymptotic regime using static encoding and predicted positive key rate out to 188 km. This can be extended to 240 km using ultra-low loss fibre based on the measured source parameters. |
