Generalized Purity and Quantum Phase Transition for Bose-Einstein condensates in a Symmetric Double Well
Thiago F. Viscondi, K. Furuya, M. C. de Oliveira
The generalized purity is employed for investigating the process of coherence loss and delocalization of the Q-function in the Bloch sphere of a two-mode Bose-Einstein condensate i…
Entanglement and the Mott insulator - superfluid phase transition in bosonic atom chains
R. J. Costa Farias, M. C. de Oliveira
We analyze the developing of bipartite and multipartite entanglement through the Mott-Insulator - Superfluid quantum phase transition. Starting from a Mott insulator state, where a…
Non-Gaussian two-mode squeezing and continuous variable entanglement of linearly and circularly polarized light beams interacting with cold atoms
R. J. Missori, M. C. de Oliveira, K. Furuya
We investigate how entangled coherent states and superpositions of low intensity coherent states of non-Gaussian nature can be generated via non-resonant interaction between either…
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…
