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…
Quantum Pulse Gate Attack on IM/DD Optical Key Distribution Exploiting Symbol Shape Distortion
M. Jarzyna, M. Jachura, K. Banaszek
Intensity modulation/direct detection (IM/DD) optical key distribution (OKD) is a method to generate a secret key whose security against passive eavesdropping is guaranteed by the…
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…
