“…In ref. 14 the authors find that the three-tangle magnitudes of the subsystem ABc and Abc are smaller than those of the subsystem ABC and abc. When we investigate the genuine tripartite nonlocalities of these subsystems, maybe the correlations of the Abc ( ) and Abc ( ) systems are not able to be tested by the Svetlichny inequalities.…”

“…In ref. 14 , the genuine tripartite entanglement dynamics was investigated via three-tangle for all the non-interaction three-qubit subsystems in a triple JCM numerically 14 . It was showed that the three-tangle ESD occurs for all non-interaction subsystems for |Φ 〉 ABC , and the three-tangle ESD does not occur for any non-interaction subsystem for GHZ-like state ABC |Ψ 〉 14 .…”

We study the genuine tripartite nonlocality of some qubit states in a triple JCM. In this model, each atom state (A, B or C) was initially prepared with an independent cavity (a, b or c). By using two kinds of GHZ-like states as the atomic initial states, we investigate the genuine tripartite nonlocality as the time evolutions for the non-interaction three-qubit subsystems. We also study the genuine tripartite nonlocality of the subsystems by using the Svetlichny inequality. For the subsystems of three atoms ABC and three cavity modes abc, we show that they are genuinely nonlocal at certain period intervals of time. The states of all the other inequivalent subsystems satisfy the Svetlichny inequality for two types of GHZ-like states.

We study on the tripartite entanglement dynamics when each party is initially entangled with other parties, but they locally interact with their own Markovian or non-Markovian environment.First, we consider three GHZ-type initial states, all of which have GHZ symmetry provided that the parameters are chosen appropriately. However, this symmetry is broken due to the effect of environment. The corresponding π-tangles, one of the tripartite entanglement measure, are analytically computed at arbitrary time. For Markovian case while the tripartite entanglement for type I exhibits an entanglement sudden death, the dynamics for the remaining cases decays normally in time with the half-life rule. For non-Markovian case the revival phenomenon of entanglement occurs after complete disappearance of entanglement. We also consider two W-type initial states.For both cases the π-tangles are analytically derived. The revival phenomenon also occurs in this case. On the analytical ground the robustness or fragility issue against the effect of environment is examined for both GHZ-type and W-type initial states. * dkpark@kyungnam.ac.kr 1 arXiv:1601.00273v2 [quant-ph]
