Long-distance quantum key distribution with on-demand single photons in the telecom-C band

Home>Research Community>Collaboration Opportunities>Partnership Resource>Long-distance quantum key distribution with on-demand single photons in the telecom-C band

Realisation of long-distance quantum key distribution (QKD) based on the BB84 protocol using telecom wavelength single photons. The aim is to optimize the pump laser stability, the down-conversion efficiency, and then implement the BB84 protocol, benchmarking the secure key rate versus fibre length and opening a path towards measurement-device-independent QKD between telecom photons generated from parametric down-conversion and the quantum dot.
