摘要:

提出了一种系统描述光的量子态偏振特性的矩展开方法。具体来说,我们链接的方法在不同方向上的庞加莱球的斯托克斯算子的测量,并提供了一种方法的偏振层析成像,而不诉诸全状态层析成像。我们将这些想法应用到一些双光子量子态的一阶和二阶偏振特性的实验。此外,我们表明,有一类状态的偏振特性不受其一阶矩(即,斯托克斯矢量),而是通过高阶偏振矩。

英文摘要:

We present a moment expansion method for the systematic characterization of the polarization properties of quantum states of light. Specifically, we link the method to the measurements of the Stokes operator in different directions on the Poincaré sphere, and provide a method of polarization tomography without resorting to full state tomography. We apply these ideas to the experimental first- and second-order polarization characterization of some two-photon quantum states. In addition, we show that there are classes of states whose polarization characteristics are dominated not by their first-order moments (i.e., the Stokes vector) but by higher-order polarization moments.
