Bright squeezed light, combining quantum noise reduction with high optical power, is a valuable resource for quantum sensing. To achieve this goal, scientists in China developed a nonclassical hybrid passive–active power stabilization technique that extends the stabilization bandwidth to MHz frequencies. They experimentally realized −5.5 dB squeezing at 1 mW across the kHz–MHz band. The novelty technique enables the new possibilities in quantum metrology and precision measurement.

Laser-driven near-infrared II (NIR-II) light sources comprising luminescent ceramics represent a promising research frontier. A non-equivalent cation substitution strategy was presented to fabricate high-efficiency translucent MgO:Ni²⁺,Cr³⁺ NIR-II luminescent ceramics. The co-doping of Cr³⁺ induces structural distortion at Ni²⁺-occupied octahedral sites, effectively breaking the parity-forbidden d-d transition constraint while enabling efficient energy transfer from Cr³⁺ to Ni²⁺. When integrated into laser-driven NIR-II light sources, the system achieves record-breaking performance of 214 mW output power under 21.43 W/mm² blue laser excitation.

Researchers have found a new way to turn low-frequency light into higher-frequency terahertz waves using special quantum materials called topological insulators. By placing these materials inside tiny ring-shaped structures that boost light signals, they created both even and odd harmonics—something rarely seen before. This breakthrough could lead to better ways of generating terahertz light, which is useful for imaging, communication, and exploring new physical effects in advanced materials.

Researchers from the Technical University of Munich have developed URNet, a novel artificial intelligence model that helps autonomous driving systems perceive their surroundings more clearly—even in dark, fast-changing environments. By combining an unconventional “event camera” with a self-aware framework, URNet allows vehicles to build reliable 3D maps that measure how far objects are—a process known as depth estimation—while understanding how confident they should be about what they “see.” This innovation could make next-generation self-driving cars safer and more capable of navigating complex real-world conditions.
