Classical capacity of phase-sensitive Gaussian quantum channels
Joachim Schäfer, Evgueni Karpov, Oleg V. Pilyavets +1
The full solution of the optimization problem giving the Gaussian capacity of the single-mode fiducial Gaussian quantum channel is provided. Since it was shown that the Gaussian ca…
Equivalence Relations for the Classical Capacity of Single-Mode Gaussian Quantum channels
Joachim Schäfer, Evgueni Karpov, Raúl García-Patrón +2
We prove the equivalence of an arbitrary single-mode Gaussian quantum channel and a newly defined fiducial channel preceded by a phase shift and followed by a Gaussian unitary oper…
Methods for Estimating Capacities and Rates of Gaussian Quantum Channels
Oleg V. Pilyavets, Cosmo Lupo, Stefano Mancini
Optimization methods aimed at estimating the capacities of a general Gaussian channel are developed. Specifically evaluation of classical capacity as maximum of the Holevo informat…
Capacities of lossy bosonic channel with correlated noise
Cosmo Lupo, Oleg V. Pilyavets, Stefano Mancini
We evaluate the information capacities of a lossy bosonic channel with correlated noise. The model generalizes the one recently discussed in [Phys. Rev. A 77, 052324 (2008)], where…
A Lossy Bosonic Quantum Channel with Non-Markovian Memory
O. V. Pilyavets, V. G. Zborovskii, S. Mancini
We provide a simple and realistic model to study memory effects in a lossy bosonic quantum channel over arbitrary number of uses. The noise correlation among different uses is intr…
Probability Representation of Quantum Mechanics: Comments and Bibliography
V. I. Man'ko, O. V. Pilyavets, V. G. Zborovskii
The probability representation of states in standard quantum mechanics where the quantum states are associated with fair probability distributions (instead of wave function or dens…
