- 1Physicists Create Record-Breaking Quantum 'Schrödinger's Cat' State●Physicists Created a Record-Breaking Schrödinger's Cat With Some of The Weirdest Atoms in Physics
Physicists report creating a record-breaking Schrödinger's cat state, a quantum system placed in a superposition of two very different states at once, using some of the most unusual atoms known in physics. The advance pushes the boundaries of how large and complex quantum superpositions can be, with potential implications for quantum computing and tests of quantum mechanics at larger scales.
- 2Jim Al-Khalili to lead 2026 Christmas Lectures on time▼Jim Al-Khalili to explore mysteries of time in 2026 Christmas Lectures
Physicist and broadcaster Jim Al-Khalili will present the 2026 Royal Institution Christmas Lectures, with the theme announced as the mysteries of time. The Lectures, a long-running British institution aimed at young audiences, have previously covered topics from chemistry to space, and the choice of time follows renewed public interest in fundamental physics. No further details about the programme or experiments have been released yet.
- 3Physicist Says Claude AI Solved a Nine-Loop Physics Problem▼A Physicist Challenged AI to Solve a Nine-Loop Problem. Claude Did It.
A physicist reports that he challenged an AI system to tackle a nine-loop problem, a famously demanding calculation in theoretical physics, and that Anthropic's Claude was able to solve it. The claim is drawing attention from researchers debating how capable large language models really are at advanced mathematics and physics, and what this means for the future of scientific work.
- 4Polish Nuclear Research Centre Leads Neutrino Study At CERN Collider●NCBJ Leads Study Of Neutrino Scattering At The Large Hadron Collider
The National Centre for Nuclear Research (NCBJ) in Poland is leading a study of neutrino scattering at the Large Hadron Collider. The work examines how neutrinos, particles that rarely interact with matter, behave during high-energy collisions, a field that has drawn growing interest since collider experiments began detecting neutrino interactions directly. Physicists see the research as a step toward understanding these elusive particles in an energy range never before accessible.
