Brookhaven National Laboratory and Stony Brook University Achieve Quantum Link Over 13 Miles
Researchers at Brookhaven National Laboratory and Stony Brook University have successfully demonstrated a quantum link across 13 miles in open air. This achievement marks the first of its kind in the United States and adds a wireless component to the nation’s longest quantum network, which spans 161 miles and connects eight nodes. The significance of this development lies in overcoming the limitations of fiber-optic cables, which can hinder the transmission of fragile quantum information over long distances. By utilizing laser technology to send quantum states of light through the atmosphere, the researchers have addressed the challenges posed by conventional wireless technology, which is unsuitable for preserving delicate quantum signals. Looking ahead, the integration of telescope technology and adaptive optics to counteract atmospheric turbulence is a noteworthy advancement. This innovative approach could pave the way for more robust quantum communication systems. No further timeline was disclosed at the time of publication.

Air Force Funds Research on Wireless Power Beaming for Military Drones to Extend Flight Time
The Air Force has initiated a research project to explore wireless power beaming for drones, led by Reach Power and the University of Nebraska-Lincoln’s NIMBUS Lab. This effort aims to enable unmanned aircraft to operate longer without needing battery swaps, enhancing their role in military communications and ISR missions. This research is significant as it addresses the critical limitation of battery life in small drones, potentially allowing them to function as persistent communication and surveillance nodes. By reducing the need for frequent landings to recharge, the project could simplify logistics and operational demands on military personnel. Looking ahead, the study will assess the feasibility of using wireless power to sustain perched drones during extended missions. A successful outcome could revolutionize military drone operations, improving battlefield communications and expanding the use of unmanned systems in intelligence, surveillance, and reconnaissance roles.
