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…
Quantum Perspective on Digital Money: Towards a Quantum-Powered Financial System
Artur Czerwinski
Quantum money represents an innovative approach to currency by encoding economic value within the quantum states of physical systems, utilizing the principles of quantum mechanics…
Quantum State Tomography of Photonic Qubits with Realistic Coherent Light Sources
Artur Czerwinski
Quantum state tomography (QST) is an essential technique for characterizing quantum states. However, practical implementations of QST are significantly challenged by factors such a…
Entanglement quantification enhanced by dark count correction
Artur Czerwinski
In this letter, we propose a method of dark count correction in quantum state tomography of entangled photon pairs. The framework is based on a linear model of dark counts, which i…
Efficiency of photonic state tomography affected by fiber attenuation
Artur Czerwinski, Jakub Szlachetka
In this article, we investigate the efficiency of photonic state tomography in the presence of fiber attenuation. The theoretical formalism of the photon loss is provided by implem…
Entanglement dynamics governed by time-dependent quantum generators
Artur Czerwinski
In the article, we investigate entanglement dynamics defined by time-dependent linear generators. We consider multilevel quantum systems coupled to an environment that induces deco…
