再论杨氏双缝实验中的自干涉

Revisiting self-interference in Young double-slit experiments

S. Kim, B. S. Ham

摘要:

量子叠加是量子力学的核心,狄拉克和费曼都提到过。在干涉系统中,单光子自干涉在过去的几十年里在量子和经典两个领域都得到了深入的研究。在玻恩定则检验中,索尔金参数表示输入光子进入干涉仪所允许的最大量子叠加数,其中多光子干涉条纹等效于激光的经典版本。在这里,一个衰减的激光在量子制度的Mach-Zehnder干涉仪中的自干涉进行了研究,并与其经典版本的结果进行了比较。由此产生的等效结果支持玻恩规则检验,其中经典干涉起源于单个单光子自干涉的叠加。这种理解揭示了二分系统之间量子特征的基本物理学。

英文摘要:

Quantum superposition is the heart of quantum mechanics as mentioned by Dirac and Feynman. In an interferometric system, single photon self-interference has been intensively studied over the last several decades in both quantum and classical regimes. In Born rule tests, the Sorkin parameter indicates the maximum number of possible quantum superposition allowed to the input photons entering an interferometer, where multi-photon interference fringe is equivalent to that of a classical version by a laser. Here, an attenuated laser light in a quantum regime is investigated for self-interference in a Mach-Zehnder interferometer, and the results are compared with its classical version. The resulting equivalent results support the Born rule tests, where the classical interference originates in the superposition of individual single-photon self-interferences. This understanding sheds light on the fundamental physics of quantum features between bipartite systems.
