摘要:

我们通过实验证明,当三个单光子通过两个偏振通道传输时,在一个定义良好的预选和后选系综中,通过弱强度测量,在同一偏振通道中没有两个光子,这是一种违反直觉的量子计数效应,称为量子鸽子悖论。我们进一步表明,这种效果打破了二阶测量。这些结果表明量子鸽子佯谬的存在及其运行机制。

英文摘要:

We experimentally demonstrate that when three single photons transmit through two polarization channels, in a well-defined pre- and postselected ensemble, there are no two photons in the same polarization channel by weak-strength measurement, a counter-intuitive quantum counting effect called quantum pigeonhole paradox. We further show that this effect breaks down in second-order measurement. These results indicate the existence of quantum pigeonhole paradox and its operating regime.
