Physicists discover a hidden “curveball” in quantum light

Researchers have experimentally demonstrated the optical Magnus effect for the first time, revealing that a tightly focused laser interacts most strongly with an atom slightly away from the beam’s center. The unexpected shift is similar to the physics that makes a spinning table tennis ball curve through the air. Because lasers are used to control qubits, the effect could create errors in quantum computers, but it might also provide a new way to couple qubits together. Full investigative context and verified commentary are published by **Science Daily**. [Read Full Story on Science Daily →](https://www.sciencedaily.com/releases/2026/09/260912220025.htm)
