摘要：
We construct a new optical field, denoted as , , by adding single-mode l-photon to a two-mode squeezed vacuum state, where is the two-mode squeezing operator. We find that its partial trace over b-mode will lead to a negative-binomial optical field in a-mode characteristic of l, which exhibits quantum entanglement. The photon number fluctuation of the new optical field both in a-mode and in b-mode is investigated. We employ the summation method within ordered product of operators to proceed our discussion.
