Superconducting nanowire single-photon detectors for quantum information

open access: yesNanophotonics, 2020
The superconducting nanowire single-photon detector (SNSPD) is a quantum-limit superconducting optical detector based on the Cooper-pair breaking effect by a single photon, which exhibits a higher detection efficiency, lower dark count rate, higher ...

Jitter analysis of a superconducting nanowire single photon detector

open access: yesAIP Advances, 2013
Jitter is one of the key parameters for a superconducting nanowire single photon detector (SNSPD). Using an optimized time-correlated single photon counting system for jitter measurement, we extensively studied the dependence of system jitter on the bias

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 ...

Multispectral Superconducting Nanowire Single-Photon Detector Based on Thickness-Modulated Optical Film Stack

open access: yesIEEE Photonics Journal, 2022
We report on a multispectral superconducting nanowire single-photon detector based on a thickness-modulated optical film stack. This unique optical film structure provides a modulated reflection bands used for single-photon detection in well-separated ...

Sub pixel resolution using spectral-spatial encoding in x-ray imaging.

open access: yesPLoS ONE, 2021
PurposePrevious efforts at increasing spatial resolution have relied on decreasing focal spot and or detector element size. Many "super resolution" methods require physical movement of a component of the imaging system.

Single-Photon Counting with Semiconductor Resonant Tunneling Devices

open access: yesNanomaterials, 2022
Optical quantum information science and technologies require the capability to generate, control, and detect single or multiple quanta of light. The need to detect individual photons has motivated the development of a variety of novel and refined single ...

Characterize the Speed of a Photon-Number-Resolving Superconducting Nanowire Detector

open access: yesIEEE Photonics Journal, 2020
Superconducting series nanowire single-photon detectors (SNDs) have been used for resolving photon numbers. But it can also exhibit a higher counting rate than a single superconducting nanowire single-photon detector (SNSPD), because the serial ...

Free-Running Single-Photon Detection via GHz Gated InGaAs/InP APD for High Time Resolution and Count Rate up to 500 Mcount/s

open access: yesMicromachines, 2023
Free-running InGaAs/InP single-photon avalanche photodiodes (SPADs) typically operate in the active-quenching mode, facing the problems of long dead time and large timing jitter.

Sequential nonabsorbing microwave single-photon detector

open access: yesPhysical Review Research, 2020
We propose a nonabsorbing microwave single-photon detector that uses an artificial atom as a coherent interaction mediator between a traveling photon and a high-Q resonator, fully exploiting the knowledge of the photon's arrival time. Our proposal can be

Mid-infrared single-pixel imaging at the single-photon level

open access: yesNature Communications, 2023
The authors present an implementation of mid-infrared single-photon computational imaging with a single-element silicon detector. In addition to unique features of single-pixel simplicity and room-temperature operation, the infrared imager offers a ...
