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-…
High Rate CV-QKD Secured Mobile WDM Fronthaul for Dense 5G Radio Networks
Dinka Milovančev, Nemanja Vokić, Fabian Laudenbach +3
A coherent transmission methodology for a continuous-variable quantum key distribution (CV-QKD) system based on quantum-heterodyne measurement through a coherent intradyne receiver…
Modelling Weak-Coherent CV-QKD Systems Using a Classical Simulation Framework
Sören Kreinberg, Igor Koltchanov, Piotr Novik +5
Due to their compatibility to existing telecom technology, continuous variable (CV) weak coherent state protocols are promising candidates for a broad deployment of quantum key dis…
Flexible Entanglement Distribution Overlay for Cloud/Edge DC Interconnect as Seed for IT-Secure Primitives
Fabian Laudenbach, Bernhard Schrenk, Martin Achleitner +3
We leverage spectral assets of entanglement and spatial switching to realize a flexible distribution map for cloud-to-edge and edge-to-edge quantum pipes that seed IT-secure primit…
Spectrally-Shaped Continuous-Variable QKD Operating at 500 MHz Over an Optical Pipe Lit by 11 DWDM Channels
D. Milovančev, N. Vokić, F. Laudenbach +3
We demonstrate high-rate CV-QKD supporting a secure-key rate of 22Mb/s through spectral tailoring and optimal use of quantum receiver bandwidth. Co-existence with 11 adjacent carri…
