TL;DR: This work demonstrates superconducting nanowire detectors atop nanophotonic waveguides, which enable a drastic increase of the absorption length for incoming photons, which allows high on-chip single-photon detection efficiency up to 91% at telecom wavelengths, repeatable across several fabricated chips.

TL;DR: It is shown how hyperentanglement allows us to deterministically distinguish between all four polarization Bell states of two photons, by realizing an optimal dense coding protocol.

TL;DR: An on-chip parametric down-conversion source of photon pairs based on second-order nonlinearity in an aluminum-nitride microring resonator is demonstrated, providing great potential for realizing sufficient on- chip filtering and monolithic integration of quantum light sources, waveguide circuits and single-photon detectors.

TL;DR: AlN-on-silicon platform for low loss, wideband optical guiding, as well as its use for achieving simultaneous high optical quality and mechanical quality optomechanical devices Exploiting AlN's inherent second order nonlinearity, they further demonstrate electro-optic modulation and efficient secondharmonic generation in AlN photonic circuits.

TL;DR: GaN has a wideband transparency window covering ultraviolet, visible and infrared wavelengths, and its platform provides a viable route for the on-chip generation of optical wavelengths in both the far infrared and near-UV through a combination of χ2 enabled sum-/difference-frequency processes.
