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…
First Demonstration of 25λ x 10 Gb/s C+L Band Classical / DV-QKD Co-Existence Over Single Bidirectional Fiber Link
Florian Honz, Florian Prawits, Obada Alia +11
As quantum key distribution has reached the maturity level for practical deployment, questions about the co-integration with existing classical communication systems are of utmost…
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…
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-…
Alignment-Tolerant Fi-Wi-Fi Free-Space Optical Bridge
Florian Honz, Aina Val Marti, Philip Walther +2
We demonstrate a simplified out-door FSO link with modal split for down-/uplink and confirm its long-term stability without active beam tracking. We further prove the duality of mo…
