AI 中文摘要
惠勒的延迟选择实验利用马赫-曾德尔干涉仪的不同实验配置展示了粒子的波粒二象性。在该实验的量子版本中，可以通过控制第二分束器的存在与否来观察光子的波粒行为。在此，我们基于纠缠光子实现了一个具有双重选择的延迟选择实验，实验上控制了马赫-曾德尔干涉仪中的两个分束器，其中第二分束器的存在与不存在通过路径编码同时控制。我们的实验揭示了单光子在两个分束器的不同配置下的波粒行为。我们进一步讨论了当两个分束器处于存在与不存在的量子叠加态时，光子将处于波粒量子叠加态的情况。
英文摘要
Wheeler's delayed-choice experiment demonstrates wave-particle duality of particles using different experimental configurations of a Mach-Zehnder interferometer. In a quantum version of this experiment, the wave-particle behavior of photons can be observed by controlling presence or absence of the second beam splitter. Here, we implement a delayed-choice experiment with dual selections based on entangled photons, experimentally controlling both of two beam splitters in the Mach-Zehnder interferometer, where the presence and absence of the second beam splitter are simultaneously controlled through path encoding. Our experiment reveals the wave-particle behavior of single photons under different configurations of two beam splitters. We further discuss the scenario when two beam splitters are in a quantum superposition of being present and absent, photons will be in a wave-particle quantum superposition state.
