论文摘要
我们研究梁路径的信息与两个脉冲光源的Hong-ou-mandel干扰有关。通过一个简单的模型，在该模型中，脉冲形式的两个光子通过梁插曲仪并在两个检测器上观察到，我们研究了如何在测量过程中删除有关两个光子路径的信息。有两种方法可以清除梁路径的信息，第一个是从一开始，在物理测量过程中，无法获得时间信息。另一个是在测量信息之后，以删除数据分析过程中的时间信息。我们表明，只有从物理测量过程中清除光束路径时，才能获得Hong-ou-mandel干扰。
We study how the information of the beam path is related to the Hong-Ou-Mandel interference with two pulsed light sources. Through a simple model in which two photons in the form of pulses pass a beamsplitter and are observed at two detectors, we investigate how, during the measurement process, information about the paths of the two photons can be erased. There are two ways to clear the information of the beam path, the first being that from the beginning, during the physical measurement process, the time information is not obtained. The other is after measuring the information, to erase the temporal information in the data analyzing process. We show that Hong-Ou-Mandel interference can be obtained only when the beam path inofrmation is cleared from the physical measurement process.
