Machine Learning based Optimization of CV-QKD Under Practical Constraints
Svitlana Matsenko, Amirhossein Ghazisaeidi, Marcin Jarzyna +4
Practical hardware limitations, including finite transmitter and receiver filter lengths as well as the finite resolution of digital-to-analog and analog-to-digital converters, lea…
Optimization of CV-QKD Under Practical Constraints
Svitlana Matsenko, Amirhossein Ghazisaeidi, Marcin Jarzyna +2
Using reinforcement learning, we optimize for practical hardware constraints, including limited FIR filter taps at the transmitter and receiver, mean photon number and finite DAC/A…
Deep-Space Optical Communication Receiver Based on Single Photon Coherent Beam Combination
Antoni Mikos-Nuszkiewicz, Karol Łukanowski, Konrad Banaszek +1
We introduce an alternative receiver architecture for deep-space optical communication, in which a single large aperture is replaced by an array of smaller ones with outputs combin…
Modeling Optical Key Distribution over a Satellite-to-Ground Link Under Weak Atmospheric Turbulence
Artur Czerwinski, Mikołaj Lasota, Marcin Jarzyna +3
In this study, we analyze the secret key capacity of intensity modulation/direct detection optical key distribution (IM/DD OKD) for a free-space optical (FSO) link between a low-Ea…
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…
Simultaneous IM/DD Data Transmission and High-Rate Secret Key Distribution over a Single C-band Channel
Michal Jachura, Jakub Szlachetka, Mateusz Kucharczyk +4
We demonstrate hierarchical multiscale PAM-4 transmission combining 500 Mbps data transfer with optical-layer cryptographic key distribution at rates 24.14 Mbps and 8.38 Mbps secur…
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…
Photon information efficiency limits in deep-space optical communications
M. Jarzyna, L. Kunz, W. Zwolinski +2
Deep-space optical communication links operate under severely limited signal power, approaching the photon-starved regime which requires a receiver capable of measuring individual…
Bayesian approach to coherent combination of single photon beams
Antoni Mikos-Nuszkiewicz, Jerzy Paczos, Konrad Banaszek +1
We theoretically investigate the performance of coherent beam combination of two light beams under relative phase fluctuations in the photon starved regime. We apply a first-princi…
Statistical uncertainty in quantum optical photodetection measurements
Konrad Banaszek
We present a complete statistical analysis of quantum optical measurement schemes based on photodetection. Statistical distributions of quantum observables determined from a finite…
