文摘
We investigate theoretically the nonclassical properties of the nonlocal coherent two-mode photon-added squeezed thermal state such as cross correlation function, antibunching effect, and inseparability. The results show the excitation number has significant effect on these properties. The cross anticorrelation effect will strengthen with decreasing of the excitation number but the cross correlation effect will weaken with decreasing of the excitation number. The antibunching effect of two-mode optical fields can be observed only if the excitation number S < 2. The entanglement between two modes of optical fields can be observed only if s ≤ 2.
