Waveguide single-photon detectors for integrated quantum photonic circuits [PDF]

, 2011
The generation, manipulation and detection of quantum bits (qubits) encoded on single photons is at the heart of quantum communication and optical quantum information processing. The combination of single-photon sources, passive optical circuits and single-photon detectors enables quantum repeaters and qubit amplifiers, and also forms the basis of all ...

High-speed thin-film lithium niobate quantum processor driven by a solid-state quantum emitter [PDF]

arXiv, 2022
Scalable photonic quantum computing architectures pose stringent requirements on photonic processing devices. The need for low-loss high-speed reconfigurable circuits and near-deterministic resource state generators are some of the most challenging requirements.

A perspective on integrated atomo-photonic waveguide circuits [PDF]

, 2021
Integrated photonic circuits based on suspended photonic rib waveguides, which can be used for coherent trapping, guiding, and splitting of ultra-cold neutral atoms in two-colour evanescent light fields near their surfaces, are described. Configurations of quantum inertial sensors based on such integrated atomo-photonic waveguides, which are ...

Controlling evanescent waves using silicon photonic all-dielectric metamaterials for dense integration

Nature Communications, 2018
Miniaturization of optical components could give way to dense photonic-integrated circuits. Here, the authors demonstrate the control of evanescent waves using all-dielectric metamaterials and show that they can reduce cross-talk and bending loss, which ...

ALD‐Assisted VO2 for Memristor Application

Advanced Engineering Materials, EarlyView.
This work demonstrates a strategy for depositing VOx using thermal atomic layer deposition (ALD) followed by thermal annealing to synthesize VO2. The thin film and core/shell wire memristors exhibit excellent switching performance and are highly sensitive to ambient temperature.
