In this paper, we consider the problem of the interaction between a two atoms and a radiation field in the squeezed coherent states with one- and two-photon processes. The analytic solution for the wavefunction of the whole system is used to describe various quantum measures. The article investigates the dynamics of entanglement between the squeezed coherent field with two atoms measured by quantum entropy. On the other side, the negativity is used to detect the atom–atom entanglement. The influence of the multiphoton transitions, the initial atomic state and intensity dependent function on the entanglement and Quantum Fisher Information (QFI) for the system under consideration is examined. Furthermore, we show how the QFI of the system states is affected and changed according to the main physical parameters. Finally, our results have reported some important phenomena such as entanglement sudden death and birth and its link with the dynamical behavior of the QFI.

在压缩相干状态下与辐射场相互作用的双原子的量子费歇尔信息和非经典性质

在本文中，我们考虑了具有一光子和二光子过程的压缩相干态中两个原子与辐射场之间的相互作用问题。整个系统波函数的解析解用于描述各种量子测度。本文研究了通过量子熵测量的两个原子的压缩相干场之间的纠缠动力学。另一方面，负性用于检测原子 - 原子纠缠。检查了多光子跃迁、初始原子状态和强度依赖函数对所考虑系统的纠缠和量子费雪信息 (QFI) 的影响。此外，我们展示了系统状态的 QFI 如何根据主要物理参数受到影响和变化。最后，
