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.
Thank you for your interest in the work of the Quantum Communications Hub (2014-2024). The project is now complete but you can still explore all our resources on this website. You can also download our legacy report through this link.
Information on the Hub’s SPOQC quantum cubesat mission, scheduled to launch in 2025, can be accessed in this section, but please note that this website will no longer be updated with new content. Information around the launch of the mission will be publicised through press releases.
