Groundbreaking Free-Space Quantum Link Transmits Entangled Photons 13 Miles!

Researchers at Brookhaven Lab and Stony Brook University achieved a historic milestone by transmitting entangled photons 13 miles through open air, marking the U.S.'s first free-space quantum link. This innovation bypasses traditional fiber optic limitations, enabling direct communication at quantum processor wavelengths. The project leverages cutting-edge adaptive optics for real-time adjustments, paving the way for a broader quantum internet. The potential applications are vast, spanning secure communications to distributed quantum computing.
