Demonstration of a next-generation wavefront actuator for gravitational-wave detection

This paper introduces FROSTI, a prototype wavefront actuator that uses thermal radiation to precisely correct mirror distortions in next-generation gravitational-wave detectors. It successfully demonstrates the device's ability to provide higher-order wavefront corrections, maintain high-intensity stability, and meet ultra-high vacuum standards, paving the way for significantly improved detector sensitivity. While promising, the system is currently a prototype optimized for a specific mirror type, and higher-power noise testing is still projected.

Probing Stress and Magnetism at High Pressures with Two-Dimensional Quantum Sensors

This study introduces a new type of quantum sensor made from a thin layer of hexagonal boron nitride (hBN) that can measure stress and magnetic fields inside a diamond anvil cell, a device used to create extremely high pressures. These sensors are more sensitive to stress than previous sensors and can be placed closer to the sample being measured, enabling more precise measurements.

3D-printed micro ion trap technology for quantum information applications

This supplementary information details the development and characterization of 3D-printed micro ion traps for quantum information applications. The authors compare the trap depth and anharmonicity of 3D-printed traps to surface traps, explore multi-ion trapping, measure heating rates, and estimate vacuum pressure within the traps.

Megapixel time-gated SPAD image sensor for 2D and 3D imaging applications

This paper presents a novel 1-megapixel single-photon avalanche diode (SPAD) camera with time-gating capabilities, enabling 2D and 3D imaging. The sensor was fabricated in 180nm CMOS technology and demonstrated time-resolved imaging with 3.8ns gating, 24kfps frame rate, and multi-object detection capability in single-photon ToF experiments.
