Squeezing-enhanced quantum key distribution over atmospheric channels
Ivan Derkach, Vladyslav C. Usenko, Radim Filip
We propose the Gaussian continuous-variable quantum key distribution using squeezed states in the composite channels including atmospheric propagation with transmittance fluctuatio…
Quantum communication with photon-number entangled states and realistic photodetection
Vladyslav C. Usenko, Matteo G. A. Paris
We address the effects of realistic photodetection, with nonunit quantum efficiency and background noise (dark counts), on the performances of quantum communication schemes based o…
Photon-number entangled states generation model with stimulated parametric down conversion
Oleksandr O. Gurin, Vladyslav C. Usenko, Constantin V. Usenko
We address the process of generation of the photon-number entangled states of light in the stimulated nonlinear parametric down conversion process and build the simple model descri…
Quantum channel based on correlated twin laser beams
Constantin V. Usenko, Vladyslav C. Usenko
This work is the development and analysis of the recently proposed quantum cryptographic protocol, based on the use of the two-mode coherently correlated states. The protocol is su…
Quantum cryptography with correlated twin laser beams
Constantin V. Usenko, Vladyslav C. Usenko
The data transmission protocol, based on the use of a strongly correlated pair of laser beams, is proposed. The properties of the corresponding states are described in detail. The…
Secure quantum channels with correlated twin laser beams
Constantin V. Usenko, Vladyslav C. Usenko
