说明量子物理学基本原理的实验室实验是强大的教学工具，因为它们重现了思想实验，让学生更深入地思考所涉及的量子力学原理。干涉、波粒二象性和纠缠是量子力学最重要的预言之一。它们是抽象的和反直觉的。最近的概念有助于说明这些微妙之处，包括量子擦除和延迟选择。在这篇文章中，我们提出了一个实验的本科实验室，涉及所有这些问题或概念。该实验只需要对一个众所周知的单光子干涉装置进行微小的修改。在这篇文章中，我们提出的实验，其结果和理论描述。
Laboratory experiments that illustrate the fundamentals of quantum physics are powerful teaching instruments because they re-enact thought experiments, allowing students to think deeper about the quantum-mechanical principles involved. Interference, wave–particle duality and entanglement are among the most important predictions of quantum mechanics. They are abstract and counter-intuitive. More recent concepts that help illustrate these subtleties include quantum erasure and delayed choice. In this article we present an experiment for the undergraduate laboratory that involves all of these issues or concepts. The experiment entails only minor modifications to a well-known setup for doing single-photon interference. In this article we present the experiment, its results and a theoretical description.
