The Short Weird Life -- and Potential Afterlife -- of Quantum Radar

sciencehabit writes: A mini-arms race is unfolding in the supposed field of quantum radar, spurred by press reports in 2016 that China had built one -- potentially threatening the ability of stealthy military aircraft to hide from conventional radars. Governments around the world have tasked physicists to look into the idea. Whereas a conventional radar searches for objects by detecting pulse of microwaves reflected from them, quantum radar would utilize pulses of microwaves linked by a quantum
