We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

Correlations are a very important tool in the study of multipartite systems, for both classical
and quantum ones. The discussion about the quantum nature of correlations permeates …

The analytical formula for the fidelity of teleportation from Alice to Bob of a thermal state used
as an input state is derived using the characteristic function approach. As a resource state it …

In this work, we calculate the exact asymptotic quantum correlations between two interacting
nonresonant harmonic oscillators in a common Ohmic bath. We derive analytical formulas …

We describe the time evolution of the fidelity of teleportation and logarithmic negativity in a
system composed of two coupled bosonic modes in contact with a thermal bath, in the …

In the present paper, we study the influence of non-commutativity on entanglement in a
system of two oscillators-modes in interaction with its environment. The considered system is …

It was recently discovered that the quantum correlations of a pair of disentangled qubits, as
measured by the quantum discord, can increase solely because of their interaction with a …

In the framework of the theory of open quantum systems based on completely positive
dynamical semigroups, we study the Gaussian quantum discord for a subsystem composed …

We describe the time evolution of logarithmic negativity, which gives the entanglement
strength of two-mode Gaussian states in terms of the covariance matrix, for a system of two …

The dynamics of quantum fidelity of two non-coupled bosonic modes interacting with a
common thermal reservoir is studied in terms of the covariance matrix, in the framework of …
