Scientists Find Weakness in Next-Gen Photonic Chips for Data Centers

Researchers discovered that photonic Chern insulators—experimental materials designed to route light in one direction without loss—become unstable when exposed to real-world impurities. The finding could delay deployment of these chips in high-speed optical networks and suggests engineers need new approaches to protect fragile quantum properties in commercial devices.
