Quantum light switch built from atomically thin mirror
Berlin, Germany (SPX) Jan 09, 2026 Controlling light across scales, from microscopes and telescopes down to nanometers, is a central challenge in modern optics. Researchers at the University of Amsterdam have now demonstrated a nanoscale mirror whose reflectivity can be switched on and off electrically using quantum effects in an atomically thin material. Physicists Tom Hoekstra and Jorik van de Groep of the UvA-Institute of Physics fabricated an actively tunable metasurface only tens to hundreds of nanometers thick. Metasurfaces a ... read more |

Conventional photon entanglement reveals thousands of hidden topologies in high dimensions
London, UK (SPX) Dec 18, 2025 Researchers at the University of the Witwatersrand in South Africa, working with Huzhou University in China, have shown that a standard source of entangled photons used in quantum optics carries a rich set of hidden topological structures in high dimensions. They report entanglement across 48 dimensions with more than 17 000 distinct topological signatures, providing a large alphabet for encoding quantum information in a way that can be robust against noise. Many quantum optics laboratories genera ... read more
