Abstract: In this article, the quantum properties of light field of the two identical two-level entangled atoms interacting with the binomialoptical field were studied by means of time evolution operator and numerical calcu lations. The results show that the time evolution of the squeezing and coherence properties of the light field depends on the entanglement degree of the initial two identical two-level entangled atoms and the parameters of the binomial optical field. The optical field fluctuation can be completely squeezed via choosing appropriate parameters.

Key words: entangled atoms, the degree of entanglement, binomial state, quantum properties of light field
