论文摘要
量子叠加是量子力学的基石,其中干扰条纹源于单个光子通过无法区分的光子特征的自身解干。在过去的几十年中,惠勒延迟选择实验已被广泛研究了波粒双重性,以了解量子力学的互补理论。延迟选择量子橡皮擦的核心是互斥的量子特征,违反了原因效应关系。在这里,我们通过将偏振器的延迟选择放在干涉仪中,使用相干光子对实验证明了量子橡皮擦。观察到的量子橡皮擦的相干溶液源自典型的Mach-Zhhnder干涉仪,在该干涉仪中,违反原因效应关系是由于基本选择的选择性测量。
Quantum superposition is the cornerstone of quantum mechanics, where interference fringes originate in the self-interference of a single photon via indistinguishable photon characteristics. Wheeler delayed-choice experiments have been extensively studied for the wave-particle duality over the last several decades to understand the complementarity theory of quantum mechanics. The heart of the delayed-choice quantum eraser is in the mutually exclusive quantum feature violating the cause-effect relation. Here, we experimentally demonstrate the quantum eraser using coherent photon pairs by the delayed choice of a polarizer placed out of the interferometer. Coherence solutions of the observed quantum eraser are derived from a typical Mach-Zehnder interferometer, where the violation of the cause-effect relation is due to selective measurements of basis choice.
