Shortwave DPS-QKD Employing a SiN Micro-Ring Resonator as Compact Quantum State Analyser
Florian Honz, Paul Müllner, Michael Hentschel +6
We show simplified DPS-QKD using a SiN micro-ring resonator operated at 852 nm. A raw-key rate of up to 25.3 kb/s is reached at a QBER suitable for secure-key extraction. Short-rea…

First Demonstration of a Group-IV Emitter on Photonic BiCMOS Supplying a Quantum Communication Link
Florian Honz, Michael Hentschel, Stefan Jessenig +3
We implement a silicon-on-insulator light emitter as optical supply for a QKD transmitter and transfer it to an electronic BiCMOS wafer. A secure key is established over short reac…
