Hemispherical array of ultrasound transducers lifts objects off reflective surfaces. Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a […]

Snapshot of five-dimensional imaging with temporal-spatial-spectral resolutions. Credit: S. Zhang, East China Normal University Spectral-volumetric compressed ultrafast photography simultaneously captures 5D information in a single snapshot. Information-rich optical imaging can provide multidimensional information to enable observation and analysis of a detected target, contributing insights into mysterious and unknown worlds. With […]

Field trial shows simple QKD system works with existing telecommunication network in Italy. In a new study, researchers demonstrate an automated, easy-to-operate quantum key distribution (QKD) system using the fiber network in the city of Padua, Italy. The field test represents an important step toward implementing this highly secure quantum […]

Researchers from Louisiana State University have introduced a smart quantum technology for the spatial mode correction of single photons. In a paper featured on the cover of the March 2021 issue of Advanced Quantum Technologies, the authors exploit the self-learning and self-evolving features of artificial neural networks to correct the distorted […]

ANIMATION The odd, wavy pattern that results from viewing certain phone or computer screens through polarized glasses has led researchers to take a step toward thinner, lighter-weight lenses. Called moiré, the pattern is made by laying one material with opaque and translucent parts at an angle over another material of […]

Credit: Maria Okuniewski / Purdue University In a feat requiring perseverance, world-leading technology, and no small amount of caution, scientists have used intense X-rays to inspect irradiated nuclear fuel. The imaging, led […]

Concept for Exawatt-class lasers. Credit: Osaka University Researchers from Osaka University propose a concept for next-generation ultra-intense lasers, possibly increasing the current record from 10 Petawatts to 500 Petawatts. Ultra-intense lasers with ultra-short pulses and ultra-high energies are powerful tools for exploring unknowns in physics, cosmology, material science, etc. With […]
