Mode Mismatch Mitigation in Gaussian-Modulated CV-QKD
Svitlana Matsenko, Amirhossein Ghazisaeidi, Marcin Jarzyna +4
Technical limitations in pulse shaping lead to mode mismatch, which significantly reduces the secure key rate in CV-QKD systems. To address this, a machine learning approach is emp…
Tx-Rx Mode Mismatch Effects in Gaussian-Modulated CV QKD
Mateusz Kucharczyk, Michal Jachura, Marcin Jarzyna +2
The impact of technical limitations on pulse shaping used to generate a CV QKD signal is quantified in terms of the attainable secure key rate. Optimization of key spectral efficie…
First Single-Carrier Transmission at Net Data Rates of 1.6 Tb/s over 9075 km and 2.4 Tb/s over 1210 km Using 300 GBd Dual-Polarization Signals and Probabilistic Constellation Shaping
Haik Mardoyan, Daniel Drayss, Sylvain Almonacil +7
We report long-haul transmissions of single-carrier 300 GBd dual-polarization signals with optical arbitrary waveform generation and measurement. We demonstrate net 1.6 Tb/s over 9…
Complexity-Aware Theoretical Performance Analysis of SDM MIMO Equalizers
Roya Gholamipourfard, Amirhossein Ghazisaeidi, Ruby Stella Bravo Ospina
We propose a theoretical framework to compute, rapidly and accurately, the signal-to-noise ratio at the output of spatial-division multiplexing (SDM) linear MIMO equalizers with ar…
