From Intra-Datacenter Interconnects to Metro Networks: Does CV-QKD Need Loss- or Bandwidth-Conscious Receivers?

Year: 2022

Type: preprint

Abstract: 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 link reach, while the latter features a 5-9 dB higher secure-key rate over short reach.
