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…
Polarization-Encoded BB84 QKD Transmitter Sourced by a SiGe Light Emitter
Florian Honz, Nemanja Vokic, Philip Walther +2
We demonstrate a polarization-encoded BB84 transmitter sourced by a SiGe light source and show that such a potentially "all-silicon" QKD scheme can operate well below the QBER thre…
