Datacom-Agnostic Shortwave QKD for Short-Reach Links
Mariana Ferreira Ramos, Marie-Christine Slater, Michael Hentschel +3
We investigate the co-existence of 852-nm and 1550-nm QKD with carrier-grade 4x25-Gb/s/ LANWDM over a short-reach interconnect. Shortwave QKD yields a higher key rate and is ins…

Simplified Polarization-Encoding for BB84 QKD Sourced by Incoherent Light of a Silicon Emitter
Florian Honz, Nemanja Vokić, Philip Walther +2
We investigate a polarization-encoded BB84-QKD transmitter that is simplified from an architectural and technological point-of-view, demonstrating a silicon emitter sourcing a low-…
