Quantum Radars Could Unstealth the F-22, F-35 and J-20 (Or Not)

In April 2018 it was reported that the Canadian Department of National Defense was investing $2.7 million in research at the University of Waterloo to investigate quantum radar technology. This brings Canada into a technological race in which China apparently has taken the lead. While Canada has opted out from acquiring F-35 stealth fighters, the North American Aerospace Defense Command (NORAD) operates jointly with the United States and must contend with potential intrusions by new Chinese and Russian stealth aircraft.
