(MilitaryAerospace) 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.
The result is quantum radar, 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.
