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 …

The actinide oxides have been extensively studied in the context of the nuclear fuel cycle.
They are also of fundamental interest as members of a class of strongly correlated materials …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Abstract Dakic, Vedral, and Brukner [arXiv: 1004.0190 (2010)] introduced a geometric
measure of quantum discord and derived an explicit formula for any two-qubit state. This …

We evaluate the quantum discord dynamics of two qubits in independent and common non-
Markovian environments. We compare the dynamics of entanglement with that of quantum …

We present a reliable algorithm to evaluate quantum discord for general two-qubit states,
amending and extending an approach recently put forward for the subclass of X states. A …

It is well known that many operations in quantum information processing depend largely on
a special kind of quantum correlation, that is, entanglement. However, there are also …

Knowledge of the dynamical behavior of correlations with no classical counterpart, like
entanglement, nonlocal correlations and quantum discord, in open quantum systems is of …

Revivals of quantum correlations have often been explained in terms of back-action on
quantum systems by their quantum environment (s). Here we consider a system of two …

We analyze the optimal measurements to access classical correlations in arbitrary two-qubit
states. Two-qubit states can be transformed into the canonical forms via local unitary …
