Detection of broadband squeezed light with a low-noise die-level balanced receiver
Emmily Zaiser, Alessandro Trenti, Dinka Milovančev +3
The generation and detection of squeezed light through spontaneous parametric down-conversion in a nonlinear crystal up to a frequency of 3.5 GHz is presented. We characterize the…
Simplified Polarization-Encoding for BB84 QKD Sourced by Incoherent Light of a Silicon Emitter
Florian Honz, Nemanja Vokić, Philip Walther +2
We investigate a polarization-encoded BB84-QKD transmitter that is simplified from an architectural and technological point-of-view, demonstrating a silicon emitter sourcing a low-…
Distribution of Telecom Entangled Photons through a 7.7 km Antiresonant Hollow-Core Fiber
Michael Antesberger, Carla M. D. Richter, Francesco Poletti +6
State of the art classical and quantum communication rely on standard optical fibers with solid cores to transmit light over long distances. However, recent advances have led to th…
Polarization-Encoded BB84 QKD Transmitter Sourced by a SiGe Light Emitter
Florian Honz, Nemanja Vokic, Philip Walther +2
We demonstrate a polarization-encoded BB84 transmitter sourced by a SiGe light source and show that such a potentially "all-silicon" QKD scheme can operate well below the QBER thre…
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…
Continuous-Variable Quantum Key Distribution with Gaussian Modulation -- The Theory of Practical Implementations
Fabian Laudenbach, Christoph Pacher, Chi-Hang Fred Fung +6
Quantum key distribution using weak coherent states and homodyne detection is a promising candidate for practical quantum-cryptographic implementations due to its compatibility wit…
