Resource-efficient real-time polarization compensation for MDI-QKD with rejected data

Olinka Bedroya, Chenyang Li, Li Qian, and Hoi-Kwong Lo

Not Accessible

Your library or personal account may give you access

Abstract

We propose and implement a novel polarization compensation in MDI-QKD systems using discarded bits, without reducing key-sharing cycle or demanding additional resources. Polarization drift is maintained below 0.15 rad over 40 km of fibre.
