We have investigated how memory effects on the teleportation of quantum Fisher information(QFI) for a single qubit system using a class of X-states as resources influenced by decoherence channels with memory, including amplitude damping, phase-damping and depolarizing channels. Resort to the definition of QFI, we first derive the explicit analytical results of teleportation of QFI with respect to weight parameter $\theta$ and phase parameter $\phi$ under the decoherence channels. Component percentages, the teleportation of QFI for a two-qubit entanglement system has also been addressed. The remarkable similarities and differences among these two situations are also analyzed in detail and some significant results are presented.

退相干下量子费雪信息隐形传态的戴维斯理论

我们已经研究了使用一类 X 态作为受具有记忆的退相干通道影响的资源的单个量子位系统的量子费雪信息 (QFI) 隐形传态的记忆效应,包括幅度阻尼、相位阻尼和去极化通道。借助 QFI 的定义,我们首先推导出 QFI 在退相干通道下相对于权重参数 $\theta$ 和相位参数 $\phi$ 隐形传态的显式分析结果。组件百分比,两个量子位纠缠系统的 QFI 隐形传态也得到了解决。还详细分析了这两种情况的显着异同,并提出了一些重要的结果。
