Robustness of Greenberger-Horne-Zeilinger and W states for teleportation in external environments
arXiv:1111.4283 · doi:10.1016/j.physleta.2010.12.058
Abstract
By solving analytically a master equation in the Lindblad form, we study quantum teleportation of the one-qubit state under the influence of different surrounding environments, and compared the robustness between Greenberger-Horne-Zeilinger (GHZ) and W states in terms of their teleportation capacity. The results revealed that when subject to zero temperature environment, the GHZ state is always more robust than the W state, while the reverse situation occurs when the channel is subject to infinite temperature or dephasing environment.
