摘要：

定义了适用于单光子两偏振态的升降算符，并利用Fock空间算符的线性变换理论，研究了BS，PBS，半波片，四分之一波片以及 H 变换等，得出了它们的算符表示，找到了新的实验表述方式，从新的角度讨论了量子信息实验，如Teleportation，分析了光子输出的各态的几率.由此总结出了一种研究和设计量子信息实验的有效方法. 

Abstract:

In this paper, we defined lowering and raising operator of single photon's two polarization states, and used the theory of linear transformation of operator in Fock space to study BS, PBS, wave plate and H transformation. We obtained their representation of operator .On the base of this; we studied some quantum information experiment, e.g. Teleportation, from a new aspect. Using the new representation, we can analyze the probability of photons output states .To do this, we try to find a new method to devise experiments much efficiently.

Key words: quantum information, Teleportation, Fock space, quantum optics, quantum information, Teleportation, Fock space
