论文摘要
基于双关式干涉仪的思想实验在开发有关波粒子二元性和玻璃纤维互补原理的想法的关键作用。理想情况下,由于光子的通过,具有足够低质量后坐力的缝隙。这种运动谴责了光线所采取的路径,并抑制了观察干扰模式的任何尝试。然而,在现实生活中,这种设置中的哪些信息可显着受到光子和缝隙的典型幅度的损害,从而几乎不可能验证效果。在这里,我们通过将类似的想法应用于Mach-Zhhnder干涉仪来扩展此讨论。也就是说,我们研究了光子通过在设备产生的干扰模式的过程中,在光子通过期间的后果。与双缝实验不同,现在可以在光子本身的波长中编码此后坐力,从原则上讲,它更容易访问。幸运的是,用于描述理想化的光束切开器和光子之间的相互作用的模型清楚地表明,基于康普顿效应的干涉仪可以构建以研究波粒二元性。我们遵循此提示,发现在这种改良的干涉仪中观察波和菌株行为之间的权衡所需的现实实验参数。
Thought experiments based on the double-slit interferometer had a crucial role to develop ideas concerning the wave-particle duality and the Bohr's complementarity principle. Ideally, a slit with a sufficiently low mass recoils due to the passage of the photon. This motion denounces the path taken by the light and suppresses any attempt to observe an interference pattern. In real life, however, available which-way information in such a setup is significantly impaired by the typical magnitudes of photons and slits, making the verification of the effect almost impossible. Here, we extend this discussion by applying similar ideas to the Mach-Zehnder interferometer. That is, we study the consequences of the beam-splitter recoil, during the passage of the photon, over the interference pattern produced by the device. Unlike the double-slit experiment, this recoil can now be encoded in the wavelength of the photon itself, which, in principle, is more easily accessed. Fortuitously, the model used to describe the interaction between the idealized beam-splitter and the photon clearly indicates that an interferometer based on Compton's effect could be build to study wave-particle duality. We follow this hint, finding realistic experimental parameters needed to observe the trade-off between wave and corpuscular behaviors in such a modified interferometer.
