Greenberger-Horne-Zeilinger态和W态在外部环境中隐形传态的鲁棒性

Robustness of Greenberger-Horne-Zeilinger and W states for teleportation in external environments

Ming-Liang Hu

摘要:

通过解析求解Lindblad形式的主方程,研究了单比特态在不同环境影响下的量子隐形传态,比较了Greenberger-Horne-Zeilinger(GHZ)态和W态的鲁棒性.结果表明,在零温度环境下,GHZ态的鲁棒性总是优于W态,而在无限温度或失相环境下,情况则相反.

英文摘要:

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.
