Coexistence of Continuous Variable Quantum Key Distribution and 7 $\times$ 12.5 Gbit/s Classical Channels

Abstract

We study coexistence of CV-QKD and 7 classical 12.5 Gbit/s on-off keying channels in WDM transmission over the C-band. We demonstrate key generation with a distilled secret key rate between 20 to 50 kbit/s in experiments running continuously over 24 hours.
