Experimental demonstration of quantum pigeonhole paradox
PNAS,2019,116(5):1549-1552 | 2019年01月29日 | https://doi.org/10.1073/pnas.1815462116
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 counterintuitive quantum counting effect called the quantum pigeonhole paradox. We further show that this effect breaks down in second-order measurement. These results indicate the existence of the quantum pigeonhole paradox and its operating regime.
