Quantum correlations in the thermodynamic limit: the XY-model
J. Batle, A. Plastino, A. R. Plastino +1
We investigate thermal properties of quantum correlations in the thermodynamic limit with reference to the XY-model
Properties of a geometric measure for quantum discord
J. Batle, A. Plastino, A. R. Plastino +1
We discuss some properties of the quantum discord based on the geometric distance advanced by Dakic, Vedral, and Brukner [Phys. Rev. Lett. {\bf 105}, 190502 (2010)], with emphasis…
Entropic Entanglement Criteria for Fermion Systems
C. Zander, A. R. Plastino, M. Casas +1
Entanglement criteria for general (pure or mixed) states of systems consisting of two identical fermions are introduced. These criteria are based on appropriate inequalities involv…
Nonlocality and entanglement in qubit systems
J. Batle, M. Casas
Nonlocality and quantum entanglement constitute two special aspects of the quantum correlations existing in quantum systems, which are of paramount importance in quantum-informatio…
