Maxwell's demons in multipartite quantum correlated systems
Helena C. Braga, Clodoaldo C. Rulli, Thiago R. de Oliveira +1
We investigate the extraction of thermodynamic work by a Maxwell's demon in a multipartite quantum correlated system. We begin by adopting the standard model of a Maxwell's demon a…
Monogamy of Quantum Discord by Multipartite Correlations
H. C. Braga, C. C. Rulli, Thiago R. de Oliveira +1
We introduce a monogamy inequality for quantum correlations, which implies that the sum of pairwise quantum correlations is upper limited by the amount of multipartite quantum corr…
Witnessing nonclassical multipartite states
A. Saguia, C. C. Rulli, Thiago R. de Oliveira +1
We investigate a witness for nonclassical multipartite states based on their disturbance under local measurements. The witness operator provides a sufficient condition for nonclass…
Global Quantum Discord in Multipartite Systems
C. C. Rulli, M. S. Sarandy
We propose a global measure for quantum correlations in multipartite systems, which is obtained by suitably recasting the quantum discord in terms of relative entropy and local von…
Entanglement and local extremes at an infinite-order quantum phase transition
C. C. Rulli, M. S. Sarandy
The characterization of an infinite-order quantum phase transition (QPT) by entanglement measures is analyzed. To this aim, we consider two closely related solvable spin-1/2 chains…
