A Scalable Platform for Massively Parallel Superconducting Single‐Photon Detection

open access: yesLaser &Photonics Reviews, EarlyView.
One hundred independent superconducting nanowire detectors, each with efficiency up to 80.1–98.3%, are integrated into a single compact system operating below 2.1 K. This parallel architecture supports fully connected multi‐user quantum entanglement distribution, while its scalability opens new avenues in optical quantum computing, QKD networks ...

Low-loss broadband antenna for efficient photon collection from a coherent spin in diamond [PDF]

open access: yes, 2014
We report the creation of a low-loss broadband optical antenna giving highly directed output from a coherent single spin in the solid state. The device, a crystalline solid-state realization of a dielectric antenna, is engineered for individual nitrogen ...

Ghost frequency-time comb LiDAR in the single photon regime [PDF]

open access: yesAPL Photonics
We experimentally demonstrate a feasible approach to light detection and ranging for low-reflecting targets using a ghost frequency-time comb (GFC). The continuous wave (CW) output beam of a fiber ring laser with half a million cavity modes is split into

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Scaling turbulence drives the general circulation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Survey on differential estimators for 3d point clouds

open access: yesComputer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...
