摘要: As an important parameter, von Neumann entropy has been used to characterize the entanglement between atom and light field. We discussed nonclassicality evolution of in a squeezed vacuum—a typical nonclassical field, compare it with that coherent state. It shows atom-field vacuum is much stronger stabler than state, whereas field depends on its initial status. This investigation trying find new insight into relation system fields. The result can be maintained well this implies better control photon mutually.
