We developed a quantum scheme of two atoms (TAs) and field initially in a negative binomial state (NBS). We displayed and discussed the physical implications of the obtained results in terms of the physical parameters of the model. By considering that the TAs were initially prepared in a maximally entangled state, and that the single-mode field was in the NBS, the dynamics of quantum phenomena such TAs-field entanglement, TAs entanglement, and parameter estimation were examined. We found that the quantum quantifiers exhibited randomly quasi-periodic and periodic oscillations that depended on the success probability, photon number transition, and the intensity-dependent coupling effect. Furthermore, we analyzed the connection between the dynamical behavior of the quantifiers. This system can be compared with some other ones that are being discussed in the literature, in order to realize the quantum entanglement, and to control the precision of the parameter estimation.
我们构建了一个由两个原子（TA）和初始处于负二项式态（NBS）的场组成的量子方案。我们根据模型的物理参数展示并讨论了所得结果的物理意义。通过考虑TA最初制备于最大纠缠态且单模场处于NBS，研究了诸如TA - 场纠缠、TA纠缠和参数估计等量子现象的动力学。我们发现量子量化器呈现出随机准周期和周期振荡，这取决于成功概率、光子数跃迁以及强度依赖耦合效应。此外，我们分析了量化器动力学行为之间的联系。为了实现量子纠缠并控制参数估计的精度，该系统可与文献中正在讨论的其他一些系统进行比较。
