中文摘要：

我们在讨论粒子数态光场在分束器上干涉后得到的输出态的量子相干性时，考虑了入射场的极化自由度。利用Campos等人提出的量子分束器的SU（2）理论模型，计算得到了输出光场所处状态的表达式。进而讨论了光场在两个不同的入射空间模上极化方向对两个输出空间模上光场二阶量子干涉度的影响。

英文摘要：

In this paper, we investigate the quantum interference of output state between two polarized Fock- State photon fields giving consideration to polarization freedom. Drawing on SU （2） mode of beam splitter found by Campos and others, we get the expression of the output state. And using this expression, we study the influence of polarization orientation in two different incidence modes on the output optical field＇s second order quantum interference degree.
