冯·诺依曼熵作为表征原子与光场纠缠态的重要参数。讨论了原子在压缩真空中的纠缠和非经典演化,并将其与相干态进行了比较。结果表明,压缩真空中的原子场纠缠比相干状态下的原子场纠缠更强、更稳定,而光场的非经典性取决于其初始状态。本研究试图对原子场系统的纠缠和光场的非经典性之间的关系找到新的认识。结果表明,在压缩真空中,原子与场之间的纠缠可以很好地保持,这意味着原子与光子之间可以更好地相互控制。
As an important parameter, von Neumann entropy has been used to characterize the entanglement between atom and light field. We discussed the entanglement and nonclassicality evolution of an atom in a squeezed vacuum—a typical nonclassical field, and compare it with that of the coherent state. It shows that the atom-field entanglement in squeezed vacuum is much stronger and stabler than that in coherent state, whereas the nonclassicality of the light field depends on its initial status. This investigation is trying to find a new insight into the relation between entanglement of atom-field system and nonclassicality of light fields. The result shows that the entanglement between the atom and the field can be maintained well in the squeezed vacuum and this implies better control of atom and photon mutually.
