TDM-based polarization and differential phase control with 35ps PMD tolerance and 20krad/s tracking speed is demonstrated. 600ns intervals are reserved for QKD and for 0{\deg}- and 45{\deg}-polarized pilot signals. ECLs are modulated directly, with high extinction. Power budget is 17dB, fiber length is 63km.

Integration of QKD in WDM networks
The theme of the integration of Quantum Key Distribution (QKD) in existing WDM optical networks will be discussed. Some evaluations about a reduced-cost implementation of BB84 protocol for QKD willExpand


20 krad/s endless optical polarisation and phase control
Presented is endless optical control not only of the state-of-polarisation of an analysed signal and its orthogonal, but also of the phase difference between the two. The normalised Stokes vectorExpand
Stable quantum key distribution with active polarization control based on time-division multiplexing
Polarization-encoding provides a promising approach for the practical quantum key distribution (QKD) system due to the simple encoding and decoding method. Here we present a long-term stableExpand
