Complete State Reconstruction of a Two-Mode Gaussian State via Local Operations and Classical Communication
Gustavo Rigolin, Marcos C. de Oliveira
We propose a strictly local quantum tomography protocol for a bipartite system. We show that the joint density matrix of an arbitrary two-mode Gaussian state, entangled or not, is…
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…
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…
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…
