AI 中文摘要
自延迟选择量子擦除的提出及Kim等人后续的实验实现以来，延迟选择实验的诠释与内涵一直是基础研究领域激烈争论的主题。本文利用标准量子力学解决了该实验相关的表观悖论。采用保留原始实验所有操作特征的扩展马赫-曾德尔干涉仪，我们证明选择路径探测器与擦除探测器的区别仅在于测量基矢的选择，并不会改写光子的过去。此外，通过将该实验映射为双向斯特恩-盖拉赫框架，我们证实量子擦除是测量纠缠态的预期结果，而非物理异常。最终，我们通过一个教学游戏说明，逆因果性的错觉源于提出了不合法的问题，而完全采用时间正向的描述即可解释其逻辑。
英文摘要
Ever since the proposal of delayed choice quantum erasure and subsequent realization in the experiment by Kim et al., the interpretation and implications of delayed-choice experiments have remained a subject of intense foundational debate. This paper resolves the apparent paradox attached to the experiment using standard quantum mechanics. Using an extended Mach-Zehnder interferometer which captures every operational feature of the original experiment, we show that choosing between which-path and erasure detectors is simply a choice of measurement bases, which does not rewrite a photon's past. Furthermore, by mapping the experiment to a two-way Stern-Gerlach framework, we prove that quantum erasure is an expected result of measuring entangled states, not a physical anomaly. Ultimately, through a pedagogical game, we illustrate that the illusion of retrocausality arises from asking illegitimate questions, and that a forward-in-time description is entirely sufficient to explain the logic.
