摘要: 本文通过利用冯诺依曼熵来研究非惯性系下的四体GHZ量子态的纠缠演化。本文假设非惯性系中的观察者是处于没有任何噪声的环境中，从而研究了当1至4个观察者加速时，其纠缠的演化关系，最后得到四体系统的冯诺依曼熵会随加速度的增大而增大。
Abstract: In this paper, we investigate the entanglement of tetrapartite GHZ state by using the von Neumann entropy in noninertial frames. We assume that the observers are in an environment without any noise and we study the entanglement when 1~4 observers are accelerated with respect to others. It is found that the von Neumann entropy of the system increases with the increasing acceleration parameter.
