Brookhaven National Laboratory and Stony Brook University have successfully demonstrated the first U.S. transmission of quantum data through open air, extending their existing fiber-optic network by 13 miles. This free-space optical link utilizes adaptive optics to counteract atmospheric turbulence, proving that quantum networks can operate beyond the physical constraints of cable infrastructure. The achievement marks a critical step toward scalable, long-distance quantum communication architectures essential for future distributed quantum computing grids.
Brookhaven Lab and Stony Brook send quantum data through the air
Brookhaven Lab & Stony Brook University sent light particles containing quantum information through open air, a first in the U.S. This advances efforts to extend quantum networks beyond fiber-optic cables.
Researchers at Brookhaven National Laboratory and Stony Brook University have achieved the first U.S. demonstration of quantum data transmitted through open air, extending the reach of the nation’s longest quantum network beyond fiber-optic cable limitations. During a demonstration on Friday, Aug. 21, scientists successfully sent light particles carrying quantum information 13 miles between the Stony Brook University’s Quantum Watchtower and Brookhaven’s Quantum Lighthouse, a rooftop facility built for this purpose. “The future of quantum information science will depend not only on what individual quantum computers and devices can do but on our ability to connect them,” said DOE Under Secretary for Science Darío Gil. This free-space optical link adds a wireless component to the network already connecting eight nodes. Brookhaven National Laboratory’s Quantum Lighthouse, a dedicated rooftop facility, served as the receiving point for the first…
