Completed: Yale Facility for Free-Space Quantum Link Across Long Island Sound
Yale University has completed an optical facility in New Haven forming the third facility in a free-space optical quantum link with Stony Brook University and Brookhaven National Laboratory. The demonstrated 13-mile Stony Brook–Brookhaven leg has transmitted quantum states and entangled photons through open air, adding wireless capability to the 161-mile fiber network. Technical details on adaptive optics, the forthcoming 30-mile Q-LATS connection, and SCY-QNet integration show the path toward extended entanglement distribution across Long Island Sound.
