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…
Monogamy Inequality and Residual Entanglement of Three Qubits under Decoherence
Thiago R. de Oliveira
Exploring an analytical expression for the convex roof of the pure state squared concurrence for rank 2 mixed states the entanglement of a system of three particles under decoheren…
Symmetry breaking effects upon bipartite and multipartite entanglement in the XY model
Thiago R. de Oliveira, Gustavo Rigolin, Marcos C. de Oliveira +1
We analyze the bipartite and multipartite entanglement for the ground state of the one-dimensional XY model in a transverse magnetic field in the thermodynamical limit. We explicit…
Coherence and Entanglement in a Stern-Gerlach experiment
Thiago R. de Oliveira, A. O. Caldeira
We give a simple example of the tight connection between entanglement and coherence for pure bipartite systems showing the double role played by entanglement; it allows for the cre…
Operational Classification and Quantification of Multipartite Entangled States
Gustavo Rigolin, Thiago R. de Oliveira, Marcos C. de Oliveira
We formalize and extend an operational multipartite entanglement measure introduced by T. R. Oliveira, G. Rigolin, and M. C. de Oliveira, Phys. Rev. A 73, 010305(R) (2006), through…
Dissipative Stern-Gerlach recombination experiment
Thiago R. Oliveira, A. O. Caldeira
The possibility of obtaining the initial pure state in a usual Stern-Gerlach experiment through the recombination of the two emerging beams is investigated. We have extended the pr…
Genuine Multipartite Entanglement in Quantum Phase Transitions
Thiago R. de Oliveira, Gustavo Rigolin, Marcos C. de Oliveira
We demonstrate that the Global Entanglement (GE) measure defined by Meyer and Wallach, J. Math. Phys. 43, 4273 (2002), is maximal at the critical point for the Ising chain in a tra…
