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 […]

UWA’s rooftop observatory.

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 […]

Schematic representation of a processor for matrix multiplications which runs on light. Credit: University of Oxford The exponential growth of data traffic in our digital age poses some real challenges on processing power. And with the advent of machine learning and AI in, for example, self-driving vehicles and speech recognition, […]

Researchers at the University of Tokyo have found a way to enhance the sensitivity of existing quantitative phase imaging so that all structures inside living cells can be seen simultaneously, from tiny particles to large structures. This artistic representation of the technique shows pulses of sculpted light (green, top) traveling […]

UV fluorescence examination. Credit: The authors Analyses of the materials in the scrolls helps put the object into a historical context and guides conservators in future restoration efforts. A picture may be worth a thousand words, but capturing multiple images of an artifact across the electromagnetic spectrum can tell a […]
