Quantum key distribution over WDMs and optical switches to combine the quantum channel with synchronization channels

Quantum key distribution over WDMs and optical switches to combine the quantum channel with synchronization channels

We use standard CWDM-telecom equipment and optical switches to combine entangled photons with all needed signalling channels and perform QKD via a single optical fiber over a distance of 25 km. (2 pages)
