Abstract summary: We show that when three single photons transmit through two polarization channels, there are no two photons in the same polarization channel by weak-strength measurement. This is a counter-intuitive quantum counting effect called quantum pigeonhole paradox.

Abstract: 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.

Tunable Einstein-Bohr recoiling-slit gedankenexperiment at the quantum limit [3.775951157440374]
We report a faithful realization of the Einstein-Bohr interferometer using a single atom in an optical tweezer. The atom has an intrinsic momentum uncertainty comparable to a single photon, which serves as a movable slit. We identify classical noise due to atom heating and precession, illustrating a quantum-to-classical transition.

Observation-dependent suppression and enhancement of two-photon coincidences by tailored losses [68.8204255655161]
Hong-Ou-Mandel (HOM) effect can lead to a perfect suppression of two-particle coincidences between the output ports of a balanced beam splitter. In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.
