Tripartite State Characterization via Activated Bipartite Entanglement
L. G. E. Arruda, W. F. Balthazar, M. V. Moreira +3
We propose a procedure to identify and classify genuine tripartite entanglement in pure 3-qubit states via the Activated Bipartite Entanglement (ABE), which is defined here as the…
Phase collapse and revival of a 1-mode Bose-Einstein condensate induced by an off-resonant optical probe field and superselection rules
L. G. E. Arruda, G. A. Prataviera, M. C. de Oliveira
Phase collapse and revival for Bose-Einstein condensates is a nonlinear phenomena appearing due atomic collisions. While it has been observed in a general setting involving many mo…
Exact dynamics of single qubit gate fidelities under the measurement-based quantum computation scheme
L. G. E. Arruda, F. F. Fanchini, R. d. J. Napolitano +2
Measurement-based quantum computation is an efficient model to perform universal computation. Nevertheless, theoretical questions have been raised, mainly with respect to realistic…
Non-Markovian Dynamics of Quantum Discord
F. F. Fanchini, T. Werlang, C. A. Brasil +2
We evaluate the quantum discord dynamics of two qubits in independent and common non-Markovian environments. We compare the dynamics of entanglement with that of quantum discord. F…
