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 …

It is known that a reliable geometric quantifier of discord-like correlations can be built by
employing the so-called trace distance, which is used to measure how far the state under …

Using the operational framework of completely positive, trace preserving operations and
thermodynamic fluctuation relations, we derive a lower bound for the heat exchange in a …

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 …

We show that two qubits, initially in a fully classical state, can develop significant quantum
correlations as measured by the quantum discord (QD) under the action of a local …

Efficient quantum-state transfer is achieved in a uniformly coupled spin-1/2 chain, with open
boundaries, by application of local magnetic fields on the second and last-but-one spins …

The distance between a quantum state and its closest state not having a certain property has
been used to quantify the amount of correlations corresponding to that property. This …

Gaussian quantum discord is a measure of quantum correlations in Gaussian systems.
Using Gaussian discord, we quantify the quantum correlations of a bipartite entangled state …

We define quantum-correlating power (QCP) of a local quantum channel acting on the left
part of a bipartite quantum system as the maximum amount of left quantum correlation that …

Beam splitters are important components in numerous tasks of quantum information
protocols used either in simple or in an interferometric arrangement or together with other …
