Key point: A real quantum radar could undo decades of work on stealth, upending the superiority of the F-22 and F-35.
KLOSTERNEUBURG, Austria – A new high-definition stealth radar system that could change the nature of warfare has been demonstrated for the first time. Popular Mechanics reports. Continue reading original article
The Military & Aerospace Electronics take:
5 Sept. 2019 -- The result, quantum radar is a high definition detection system that provides a much more detailed image of targets while itself remaining difficult to detect. Quantum radars could provide users with enough detail to identify aircraft, missiles, and other aerial targets by specific model.
Researchers at Austria’s Institute of Science and Technology in Klosterneuburg, Austria, used entangled microwaves to create one of the world’s first quantum radar system.
Under a principle known as quantum entanglement, two particles can be linked together regardless of distance, forming what scientists call a quantum entangled pair. When something happens to one particle it can be noticed in the other particle. This in turn leads to a process called quantum illumination, where information about one particle’s environment can be inferred by studying the other particle.
