Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

Journal of Field Robotics, Volume 43, Issue 2, Page 1178-1192, March 2026.ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

Sharp Diamond Needles for Single‐Photon Emission
Advanced Photonics Research, Volume 7, Issue 2, February 2026.We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.
