On the Security of Offloading Post-Processing for Quantum Key Distribution
Thomas Loruenser, Stephan Krenn, Christoph Pacher +1
Quantum key distribution (QKD) has been researched for almost four decades and is currently making its way to commercial applications. However, deployment of the technology at scal…
Long-Range QKD without Trusted Nodes is Not Possible with Current Technology
Bruno Huttner, Romain Alléaume, Eleni Diamanti +11
A recently published patent (https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2590064) has claimed the development of a novel quantum key distribution protocol purporting to…
Demonstration of 17λ x 10 Gb/s C-Band Classical / DV-QKD Co-Existence Over Hollow-Core Fiber Link
Florian Honz, Florian Prawits, Obada Alia +11
We successfully integrate coherent one-way QKD at 1538 nm in a 7.7 km long hollow-core fiber link with 17 EDFA-boosted C-band data channels from 1540.56 to 1558.17 nm, aggregating…
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…
Towards metropolitan free-space quantum networks
Andrej Kržič, Sakshi Sharma, Christopher Spiess +18
Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre based systems h…
Differential Phase-Shift QKD in a 2:16-Split Lit PON with 19 Carrier-Grade Channels
Nemanja Vokiic, Dinka Milovanvcev, Bernhard Schrenk +2
We investigate the practical network integration of differential phase shift quantum key distribution following a cost-optimized deployment scheme where complexity is off-loaded to…
