From Intra-Datacenter Interconnects to Metro Networks: Does CV-QKD Need Loss- or Bandwidth-Conscious Receivers?
Florian Honz, Fabian Laudenbach, Hannes Hübel +2
We experimentally compare a loss-optimized coherent heterodyne and a bandwidth-blessed intradyne CV-QKD architecture. We find the former to prevail performance-wise for medium/long…

Ultra-Low Noise Balanced Receiver with >20 dB Quantum-to-Classical Noise Clearance at 1 GHz
Dinka Milovančev, Florian Honz, Nemanja Vokić +3
We demonstrate a die-level balanced homodyne receiver for coherent optical access and continuous-variable quantum applications, featuring a 40dB CMRR up to 1GHz and a high quantum-…

Broadband Balanced Homodyne Detector for High-Rate (>10 Gb/s) Vacuum-Noise Quantum Random Number Generation
Florian Honz, Dinka Milovančev, Nemanja Vokić +2
We demonstrate a die-level balanced homodyne detector with a high quantum-to-classical noise clearance of 19.1dB over 3GHz bandwidth. We evaluate this receiver as a high-quality en…
