High-Rate Continuous Variable Quantum Key Distribution Based on Probabilistically Shaped 64 and 256-QAM
François Roumestan, Amirhossein Ghazisaeidi, Jérémie Renaudier +3
We designed a CV-QKD system with off-the-shelf components and established the feasibility of distributing 67.6 and 66.8 Mb/s secret key rates on average over a 9.5 km SMF link, usi…
Demonstration of Probabilistic Constellation Shaping for Continuous Variable Quantum Key Distribution
François Roumestan, Amirhossein Ghazisaeidi, Jérémie Renaudier +3
We demonstrate, for the first time to our knowledge, continuous-variable quantum key distribution using probabilistically-shaped 1024-QAM and true local oscillator, achieving 38.3M…
Revisiting Born's rule through Uhlhorn's and Gleason's theorems
Alexia Auffeves, Philippe Grangier
In a previous article [1] we presented an argument to obtain (or rather infer) Born's rule, based on a simple set of axioms named "Contexts, Systems and Modalities" (CSM). In this…
Revisiting Quantum Mysteries
Philippe Grangier
In this article we argue that in quantum mechanics, and in opposition to classical physics, it is impossible to say that an isolated quantum system "owns" a physical property. Some…
