Asymmetry effects in homodyne and heterodyne measurements: Positive operator-valued measures and asymptotic security of Gaussian-continuous-variable quantum key distribution
A. S. Naumchik, Roman K. Goncharov, Alexei D. Kiselev
We use the Gaussian approximation describing photocount statistics for both the homodyne and the double homodyne (heterodyne) measurements to study asymmetry effects arising from i…

Sub-Poissonian light in fluctuating thermal-loss bosonic channels
Iliya G. Stepanov, Roman K. Goncharov, Alexei D. Kiselev
We study the photon statistics of a single-mode sub-Poissonian light propagating in the temperature-loss bosonic channel with fluctuating transmittance which can be regarded as a t…
