摘　　要：通过对一种特殊的光子回波实验得到的二维三阶非线性复相光谱研究,提出了一种识别不同相干叠加态光子的方法.实验步骤为:首先将光子(激光)输入光纤,让其通过光纤;然后以光纤输出的激光器为光源,进行光子回波实验;最后从光子回波信号中得到二维三阶非线性的复相谱.根据得到的二维三阶非线性复相谱图形,确定输入光子处于何种量子态.In this paper, we propose a scheme to identify photons with different coherent superposition states through studying 2D, third-order, non-linear rephasing spectra acquired from a special photon echo experiment. The procedures of the experiment can be arranged as follows: Photons (laser) are first input into a fiber, letting them pass through the fiber. Next, the output laser is taken from the fiber as the light source to conduct the photon echo experiment. Finally, the 2D, third-order, non-linear rephasing spectra can be obtained from the photon echo signals. Based on the pattern of the spectra, the quantum states of the input photons can thus be determined.
