论文摘要
量子力学的心脏是单个粒子的正交碱基之间的量子叠加。在量子力学的粒子性质中，量子叠加由互斥性质（例如正交极化碱基）之间的概率幅度表示。延迟选择的量子橡皮擦是用于对光子性质的确定性的，从而增加了原因效应关系问题。在过去的几十年中，使用几乎所有类型的光子对量子橡皮擦进行了深入的研究。在这里，使用连续的波激光器在实验上证明了宏观延迟选择量子橡皮擦，并在宏观方向上讨论了量子叠加。为此，选择由两个极化束拆分器组成的非换压马赫德干涉仪可操纵光的极化底座，并通过极化基线投影以延迟选择的方式进行测量。
The heart of quantum mechanics is quantum superposition between orthogonal bases of a single particle. In the particle nature of quantum mechanics, quantum superposition is represented by probability amplitudes between mutually exclusive natures such as orthogonal polarization bases. The delayed-choice quantum eraser is for the post-determination of the photon nature, raising the cause-effect relation issue. Over the last several decades, quantum erasers have been intensively studied using nearly all kinds of photons. Here, the macroscopic delayed-choice quantum eraser is experimentally demonstrated using a continuous wave laser and discussed for quantum superposition in a macroscopic regime. For this, a noninterfering Mach-Zehnder interferometer composed of two polarizing beam splitters is chosen to manipulate polarization bases of lights and to measure them in a delayed-choice manner via polarization-basis projection.
