- Abstract: We study how to achieve, manipulate, and switch classical or quantum
nonreciprocal effects of light with a spinning Kerr resonator. In particular,
we show that even when there is no classical nonreciprocity (i.e., with the
same mean number of photons for both clockwise and counterclockwise propagating
modes), it is still possible to realize nonreciprocity of quantum correlations
of photons in such a device. Also, by tuning the angular velocity and the
optical backscattering strength, higher-order quantum nonreciprocity can
appear, featuring qualitatively different third-order optical correlations,
even in the absence of any nonreciprocity for both the mean photon number and
its second-order correlations. The possibility to switch a single device
between a classical isolator and a purely quantum directional system can
provide more functions for nonreciprocal materials and new opportunities to
realize novel quantum effects and applications, such as nonreciprocal
multi-photon blockade, one-way photon bundles, and backaction-immune quantum
communications.

Hong-Ou-Mandel effect is a paradigmatic quantum phenomenon demonstrating the interference of two indistinguishable photons that are linearly coupled at a 50:50 beam splitter.
Here, we transpose such a two-particle quantum interference effect to the nonlinear regime, when two single photons are impinging on a parametric down-conversion crystal.
We experimentally demonstrate the suppression of the probability of detecting precisely one photon pair when the amplification gain is tuned to 2, which arises from the destructive interference between the transmitted and reborn photon pairs.

Indistinguishability is an essential concept to understanding mysterious quantum features in the view point of the wave-particle duality of quantum mechanics.
