标题： Quantum polarization characterization and tomography

摘要： 我们提供了对两个正交偏振模式的任何量子态的完整偏振表征，并给出了系统测量程序以收集必要的数据。 完全表征需要在两种模式中测量光子数和线性光学。 在只能确定光子数差的情况下，可以获得有限但有用的表征。 给出了几种常见量子态的特征斯托克斯矩分布。 显示英文摘要

摘要： We present a complete polarization characterization of any quantum state of two orthogonal polarization modes, and give a systematic measurement procedure to collect the necessary data. Full characterization requires measurements of the photon number in both modes and linear optics. In the situation where only the photon-number difference can be determined, a limited but useful characterization is obtained. The characteristic Stokes moment profiles are given for several common quantum states.
