In this paper, we study the dynamics of quantum Fisher information of a qubit interacting with a squeezed thermal environment. We obtain the optimal initial state of the qubit, the temperature of the environment, and the interaction time, which maximize quantum Fisher information. Based on the ohmicity of the environment, we compare the dynamics of quantum Fisher information in ohmic, sub-ohmic, and super-ohmic regimes of the environment. We investigate the estimation of temperature, squeezing amplitude and phase of the environment in detail by studying the behavior of quantum Fisher information. Furthermore, it is shown that the behavior of quantum Fisher information strongly depends on the ohmicity parameter and also the squeezing amplitude of the environment.

在本文中，我们研究了与压缩热环境相互作用的量子位的量子 Fisher 信息的动力学。我们获得了量子比特的最佳初始状态、环境温度和交互时间，从而最大化了量子 Fisher 信息。基于环境的欧姆性，我们比较了环境的欧姆、亚欧姆和超欧姆状态下量子 Fisher 信息的动力学。我们通过研究量子 Fisher 信息的行为，详细研究了环境的温度、挤压幅度和相位的估计。此外，还表明量子Fisher信息的行为强烈依赖于欧姆参数以及环境的挤压幅度。
