LQuNet a reflective QKD system based on DPS (Differential Phase-Shift), has been developed within the WWTF project. LQuNet is aimed at applications in Passive Optical Networks (PON) and Local Area Networks (LAN). The QKD system is laid out conceptually in such a way that complexity and cost is centralized at a shared line terminal acting as the (Alice-side) head-end of the QKD links. In this way, economically viable deployment of low-cost (Bob-side) QKD transmitters based on telecom-grade components can be guaranteed.
