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…
Optimal Probing Sequences for Polarization-Multiplexed Coherent Phase OTDR
Christian Dorize, Elie Awwad, Sterenn Guerrier +1
We introduce dual-polarization probing codes based on two circularly shifted frequency sweep signals enabling perfect channel estimation. This is achieved with a probing length equ…
Towards Polarization-Insensitive Coherent Coded Phase OTDR
Sterenn Guerrier, Christian Dorize, Elie Awwad +1
We explore the alternatives for interrogating a fiber sensor from the polarization point of view, and demonstrate a better accuracy with dual polarization probing for coherent phi-…
On the Comparison of Single-Carrier vs. Digital Multi-Carrier Signaling for Long-Haul Transmission of Probabilistically Shaped Constellation Formats
Kaoutar Benyahya, Amirhossein Ghazisaeidi, Vahid Aref +6
We report on theoretical and experimental investigations of the nonlinear tolerance of single carrier and digital multicarrier approaches with probabilistically shaped constellatio…
