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…
Advantages and limitations of channel multiplexing for discrete-variable quantum key distribution
Indranil Maiti, Mikołaj Lasota
Typically practical realizations of discrete-variable quantum key distribution (QKD) protocols, based on exchanging single-photon signals between the trusted parties, can provide i…
Robustness of entanglement-based discrete- and continuous-variable quantum key distribution against channel noise
Mikolaj Lasota, Olena Kovalenko, Vladyslav C. Usenko
Discrete-variable (DV) and continuous-variable (CV) schemes constitute the two major families of quantum key distribution (QKD) protocols. Unfortunately, since the setup elements r…
Optimization of intensity-modulation/direct-detection optical key distribution under passive eavesdropping
Konrad Banaszek, Michal Jachura, Piotr Kolenderski +1
We analyze theoretically optimal operation of an optical key distribution (OKD) link based on fine intensity modulation of an optical signal transmitted over an attenuating channel…
Optimal photon pairs for quantum communication protocols
Miko\{l}aj Lasota, Piotr Kolenderski
We theoretically investigate the problem of finding optimal characteristics of photon pairs, produced in the spontaneous parametric down-conversion (SPDC) process, for fiber-based…
Remote temporal wavepacket narrowing
K. Sedziak, M. Lasota, P. Kolenderski
Quantum communication and clock synchronization protocols can be significantly enhanced by the careful preparation of the wavepackets of the produced photons. Following the theoret…
Quantum communication improved by spectral entanglement and supplementary chromatic dispersion
Mikołaj Lasota, Piotr Kolenderski
Implementations of many quantum communication protocols require sources of photon pairs. However, optimization of the properties of these photons for specific applications is an op…
Reducing detection noise of a photon pair in a dispersive medium by controlling its spectral entanglement
Karolina Sedziak, Mikołaj Lasota, Piotr Kolenderski
Chromatic dispersion is one of the main limitations to the security of quantum communication protocols that rely on the transmission of single photons in single mode fibers. This p…
Sufficiency of quantum non-Gaussianity for discrete-variable quantum key distribution over noisy channel
Mikołaj Lasota, Radim Filip, Vladyslav C. Usenko
Quantum key distribution can be enhanced and extended if nonclassical single-photon states of light are used. We study a connection between the security of quantum key distribution…
Robustness of quantum key distribution with discrete and continuous variables to channel noise
Mikołaj Lasota, Radim Filip, Vladyslav C. Usenko
We study the robustness of quantum key distribution protocols using discrete or continuous variables to the channel noise. We introduce the model of such noise based on coupling of…
Linear optics schemes for entanglement distribution with realistic single-photon sources
Mikołaj Lasota, Czesław Radzewicz, Konrad Banaszek +1
We study the operation of linear optics schemes for entanglement distribution based on nonlocal photon subtraction when input states, produced by imperfect single-photon sources, e…

Mikolaj Lasota, Rafal Demkowicz-Dobrzanski, Konrad Banaszek
We analyze theoretically performance of four-state quantum key distribution protocols implemented with a realistic heralded single-photon source. The analysis assumes a noisy model…
