TL;DR: An overview of the most recent developments and improvements to the low-loss TriPleX Si3N4 waveguide technology is presented in this article, which can be combined to design complex functional circuits, but more important are manufactured in a single monolithic flow to create a compact photonic integrated circuit.

TL;DR: In this paper, a scalable method employing a random unitary chip and a quantum walk chip is developed to experimentally verify correct operation for large-scale boson sampling, and the resulting statistics of the output of a linear interferometer fed by indistinguishable single-photon states exhibits true nonclassical characteristics.

TL;DR: TriPleX as discussed by the authors is a dielectric waveguide platform based on alternating silicon nitride and silicon dioxide films, which can achieve low-loss waveguides over a wide wavelength range (400 nm-2.35 μm).

TL;DR: In this article, the authors describe the design of a waveguiding structure, demonstrate the practical feasibility of realizing this structure, and discuss the preliminary measurement results, which is a very versatile material, which can be designed having the potential of meeting all those requirements.

TL;DR: Erbium-doped aluminum oxide integrated optical amplifiers were fabricated on silicon substrates, and their characteristics were investigated for Er concentrations ranging from 0.27 to 4.2×1020 cm−3.
