Entanglement of Tripartite States with Decoherence in Noninertial frames
arXiv:1302.3005 · doi:10.1080/09500340.2011.625476
Abstract
The one-tangle and π-tangle are used to quantify the entanglement of a tripartite GHZ state in noninertial frames when the system interacts with a noisy environment in the form of phase damping, phase flip and bit flip channel. It is shown that the two-tangles behave as a closed system. The one-tangle and π-tangle have different behaviors in the three channel. In the case of phase damping channel, depending on the kind of coupling, the sudden death of both one-tangle and π-tangle may or may not happen. Whereas in the case of phase flip channel the sudden death cannot be avoided. The effect of decoherence may be ignored in the limit of infinite acceleration when the system interacts with a bit flip channel. Furthermore, a sudden rebirth of the one-tangle and π-tangle occur in the case of phase flip channel that may be delayed when collective coupling is switched on.
