Cutting a photon in two creates an infinite swarm of particles
June 2, 2026 report Cutting a photon in two creates an infinite swarm of particles Sam Jarman Author Gaby Clark Scientific Editor Robert Egan Associate Editor By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway for a single photon. The answer is deeply strange: attempting to cut a photon in two wouldn't produce two smaller...
Quantum circuits help AI overcome memory limitations with minimal new parameters
June 7, 2026 report Quantum circuits help AI overcome memory limitations with minimal new parameters Sam Jarman Author Gaby Clark Scientific Editor Robert Egan Associate Editor For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive. Through a new preprint on the arXiv server, a team led by Borja Aizpurua at...
Gold nanoparticles unlock vibrant structural colors across the visible spectrum
June 7, 2026 report Gold nanoparticles unlock vibrant structural colors across the visible spectrum Sam Jarman Author Gaby Clark Scientific Editor Robert Egan Associate Editor Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues at KU-KIST in Seoul have developed a new approach that overcomes this limitation, producing...
Quantum light gives a 20-fold boost to ultrafast laser processes
May 30, 2026 report Quantum light gives a 20-fold boost to ultrafast laser processes Sam Jarman Author Gaby Clark Scientific Editor Robert Egan Associate Editor Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a fundamental constraint: the stronger you make the laser, the more likely it is to destroy whatever it illuminates. Through new experiments...
