If you think you can go stealth, guess again. I’m looking at you F-35s and F-117. Them pesky, dangerous Canadians are looking to create a quantum radar that would totally expose the stealthiest of stealth and make you naked before the whole world.
|Quantum Radar Could Make Stealth Technology Obsolete|

The phenomenon known as “quantum entanglement,” which involves creating pairs or groups of particles whose fates are forever tied, might hold to key to seeing through stealth aircraft’s radio-repelling shields.
But a functional quantum radar has never been tested outside of the lab. This week, researchers at the University of Waterloo in Ontario, Canada announced that they’re taking a big step forward in doing just that.
“The goal for our project is to create a robust source of entangled photons that can be generated at the press of a button,” Jonathan Baugh, a faculty member at the University of Waterloo’s Institute for Quantum Computing (IQC), said in a statement. “This project will allow us to develop the technology to help move quantum radar from the lab to the field. It could change the way we think about national security.”
But what do photons, or light particles, have to do with detecting stealth aircraft and missiles? It all hinges on the mysterious behavior of entangled particles, which have puzzled physicists since Einstein’s time.
In quantum physics, “entangled” particles are two particles (like photons) that have a special connection. When a force or action changes one particle, the paired particle instantaneously changes too, even if the two particles are separated by huge distances — say, 100,000 light-years apart.
For such a change to occur, particles have to somehow correlate their states with each other faster than the speed of light, which really bothered Einstein. (He famously called the whole phenomenon “spooky action at a distance.”) Still, more recent experiments have shown that spooky action at a distance really does seem to happen.
