In this paper, we investigate the decoherence of GHZ state under three noisy channels in non-inertial frames. The phase flip, the bit flip and the phase damping channels are considered as noisy channels, respectively. By using three-tangle τ as the measurement of entanglement, we numerically calculate the genuine tripartite entanglement of GHZ state under noisy environments in non-inertial frames. Unlike the case of phase damping channel, in the cases of the phase flip and the bit flip ones, we find that the effect of environment cannot only decay the genuine tripartite entanglement, but also revive it.

非惯性帧中三个噪声通道下 GHZ 状态的退相干

在本文中，我们研究了非惯性帧中三个噪声通道下 GHZ 状态的退相干性。相位翻转、位翻转和相位阻尼通道分别被认为是噪声通道。通过使用三缠τ作为纠缠的测量，我们数值计算了非惯性框架中噪声环境下GHZ状态的真正三方纠缠。与相位阻尼通道的情况不同，在相位翻转和比特翻转的情况下，我们发现环境的影响不仅可以衰减真正的三方纠缠，还可以恢复它。
