Single-Photon Nanoantennas [PDF]

open access: yesACS Photonics, 2017
Single-photon nanoantennas are broadband strongly scattering nanostructures placed in the near field of a single quantum emitter, with the goal to enhance the coupling between the emitter and far-field radiation channels. Recently, great strides have been made in the use of nanoantennas to realize fluorescence brightness enhancements, and Purcell ...

Topological photonics for single-photon sources. [PDF]

open access: yesLight Sci Appl
Abstract The pursuit of high-quality single-photon sources has long been hampered by challenges in improving the performance and robustness. While traditional microcavity structures can achieve impressive performance, they suffer from extreme sensitivity to manufacturing uncertainty, structural disorders, and ...

Photonic Jets and Single‐Photon Emitters

open access: yesAdvanced Photonics Research, 2022
Photonic jets (PJs) obtained by illuminating a dielectric microsphere have recently shown to provide an efficient and cost‐effective means of laser‐writing and localizing single‐photon emitters with sub‐diffraction precision.

Single photon event-driven 3D imaging [PDF]

open access: yesCommunications Engineering
Event-based imaging is at the forefront of high-speed sensing applications due to the low latency of asynchronous detection and low data volume. Conventionally, events used in this form of sensing correspond to changes in intensity on the microsecond ...

Single-photon vibrometry [PDF]

open access: yesOptics Letters, 2021
We propose and demonstrate a single-photon sensitive technique for optical vibrometry. It uses high speed photon counting to sample the modulated backscattering from a vibrating target. Designed for remote vibration sensing with ultralow photon flux, we show that this technique can detect small displacements down to 110 nm and resolve vibration ...

Single-photon microwave photonics

open access: yesScience Bulletin, 2022
With the rapid development of microwave photonics technology, high-speed processing and ultra-weak signal detection capability have become the main bottlenecks in many applications. Thanks to the ultra-weak signal detection capability and the extremely low timing jitter properties of single-photon detectors, the combination of single-photon detection ...

Single atom photon pair source [PDF]

open access: yesEPJ Web of Conferences, 2022
Sources of entangled photon pairs are a crucial ingredient for many applications in quantum information and communication. Of particular interest are narrow-band sources with bandwidths that are compatible with solid state systems such as atomic media ...

Solve single photon detector problems [PDF]

open access: yesQuantum, 2023
Single photon detector(SPD) problems arise in most quantum tasks, especially for measuring states going through high-lost channels. They are particularly prominent in quantum key distribution(QKD), which could be the most significant application in ...

Semi-Quantum Identification without Information Leakage

open access: yesMathematics, 2023
In 2019, Zhou et al. proposed semi-quantum identification (also known as semi-quantum authentication, SQA), which proceeds under a measure-resend and measurement-free environment.

Wet-Etched Microlens Array for 200 nm Spatial Isolation of Epitaxial Single QDs and 80 nm Broadband Enhancement of Their Quantum Light Extraction

open access: yesNanomaterials, 2021
Uniform arrays of three shapes (gauss, hat, and peak) of GaAs microlenses (MLs) by wet-etching are demonstrated, ∼200 nm spatial isolation of epitaxial single QDs embedded (λ: 890–990 nm) and broadband (Δλ∼80 nm) enhancement of their quantum light ...
