在非惯性系下开放环境中的四体纠缠
Tetrapartite Entanglement of an Open Quantum System in Accelerated Frames
摘要:
本文主要研究了四体GHZ量子态在开放环境中非惯性系下的纠缠变化，探究了当三个观察者加速时，系统A和系统AB与环境接触时，纠缠的变化情况。接着探究了当四个观察者加速时，只有系统A与环境接触时，它们的纠缠变化情况。
Abstract:
In this paper, we mainly study the entanglement of tetrapartite GHZ quantum states in an open environment in a noninertial system, and explore the entanglement changes when the three observers accelerate, and when the system A and system AB contact with the environment. Then we explore the entanglement changes of four observers when they all accelerate, only when the system A contacts the environment.
