Enabling Shortwave-QKD in Short-Reach Networks: Impact of a Composite ODN Native to Telecom Applications
Mariana F. Ramos, Costin Luchian, Michael Hentschel +4
We deploy shortwave-QKD over short-reach in-house/datacom architectures and show that few-mode propagation and speckle-selective loss severely impact the QKD performance. We accomp…

Detection of broadband squeezed light with a low-noise die-level balanced receiver
Emmily Zaiser, Alessandro Trenti, Dinka Milovančev +3
The generation and detection of squeezed light through spontaneous parametric down-conversion in a nonlinear crystal up to a frequency of 3.5 GHz is presented. We characterize the…

Towards an All-Silicon QKD Transmitter Sourced by a Ge-on-Si Light Emitter
Florian Honz, Nemanja Vokić, Michael Hentschel +3
We demonstrate a novel transmitter concept for quantum key distribution based on the polarization-encoded BB84 protocol, which is sourced by the incoherent light of a forward-biase…
