Inter-Core Crosstalk Impact of Classical Channels on CV-QKD in Multicore Fiber Transmission

11 Jan 2019 · Eriksson Tobias A., Puttnam Benjamin J., Rademacher Georg, Luis Ruben S., Takeoka Masahiro, Awaji Yoshinari, Sasaki Masahide, Wada Naoya ·

Crosstalk-induced excess noise is experimentally characterized for continuous-variable quantum key distribution, spatially multiplexed with WDM PM-16QAM channels in a 19-core fiber. The measured noise-sources are used to estimate the secret key rates for different wavelength channels.
