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 study of Gaussian states has arisen to a privileged position in continuous variable
quantum information in recent years. This is due to vehemently pursued experimental …

In this Letter we exploit the recently solved conjecture on the bosonic minimum output
entropy to show the optimality of Gaussian discord, so that the computation of quantum …

The central issue in quantum parameter estimation is to find out the optimal measurement
setup that leads to the ultimate lower bound of an estimation error. We address here a …

Weak measurements cause small change to quantum states, thereby opening up the
possibility of new ways of manipulating and controlling quantum systems. We ask, can weak …

Quantum information processing leverages the principles of quantum mechanics, utilizing
qubits, to improve computational and communicative tasks. In this realm, the quantum …

We study the dynamics of heat flux in the thermalization process of a pair of identical
quantum systems that interact dissipatively with a reservoir in a cascaded fashion. Despite …

We investigate the amount of entanglement and quantum discord extractable from a two-
mode squeezed state as considered from the viewpoint of two observers, Alice (inertial) and …

We study the harvesting of quantum and classical correlations from a hot scalar field in a
periodic cavity by a pair of spatially separated oscillator-detectors. Specifically, we utilize …

Combining two entanglement-breaking channels into a correlated-noise environment
restores the distribution of entanglement. Surprisingly, this reactivation can be induced by …
