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…
World's First Monolithic SiGe QKD Transmitter Chip
Florian Honz, Winfried Boxleitner, Mariana Ferreira-Ramos +4
We present a single-chip photonic QKD transmitter fabricated on a silicon platform. We achieve secure-key generation over 45.9km of field-deployed fiber and prove its operation alo…
FPA Beamforming for Alignment-Tolerant FSO QKD Links
Florian Honz, Winfried Boxleitner, Michael Hentschel +3
We demonstrate focal plane array beamforming for semi-blind deployments of free-space optical QKD links. We accomplish a secure-key rate of 1.2 kb/s at a QBER of 9.1% over a 63-m o…
Solar-Blind QKD over Simplified Short-Range FSO Link
Florian Honz, Michael Hentschel, Philip Walther +2
We demonstrate QKD and data communication over an out-door free-space link where large-core fiber substitutes active alignment. We further prove E-band QKD as stable and robust und…
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…
Towards an All-Silicon DV-QKD Transmitter Sourced by a Ge-on-Si Light Emitter
Florian Honz, Nemanja Vokić, Philip Walther +2
We investigate the behavior of a Ge-on-Si light source and demonstrate its feasibility for polarization-encoded discrete-variable quantum key distribution following the BB84 protoc…
