The photon statistics emitted by a large variety of light‐matter systems under weak coherent
driving can be understood, to lowest order in the driving, in the framework of an admixture of …

This article reviews recent progress in quasi-phasematched $\chi^{(2)} $ nonlinear
nanophotonics, with a particular focus on dispersion-engineered nonlinear interactions …

The absence of the single-photon nonlinearity has been a major roadblock in develo**
quantum photonic circuits at optical frequencies. In this paper, we demonstrate a periodically …

The hybrid microwave optomechanical-magnetic system has recently emerged as a
promising candidate for coherent information processing because of the ultrastrong …

Photonic nanostructures simultaneously maximizing spectral and spatial overlap between
fundamental and second-harmonic confined modes are highly desirable for enhancing …

We show that relatively simple integrated photonic circuits have the potential to realize a
high fidelity deterministic controlled-phase gate between photonic qubits using bulk optical …

We study the photon blockade at exceptional points for a non-Hermitian optomechanical
system coupled to the driven whispering-gallery-mode microresonator with two …

The photon blockade based on weak nonlinearities is called the unconventional photon
blockade. The study of the unconventional photon blockade in recent decades has mainly …

Second-harmonic generation in nonlinear materials can be greatly enhanced by realizing
doubly resonant cavities with high quality factors. However, fulfilling such doubly resonant …

It is shown that noncentrosymmetric materials with bulk second-order nonlinear
susceptibility can be used to generate strongly antibunched radiation at an arbitrary …
