Technology to improve national defence
Quantum radar uses a sensing technique called quantum illumination to detect and receive information about an object. At its core, it leverages the quantum principle of entanglement, where two photons form a connected, or entangled, pair.
The method works by sending one of the photons to a distant object, while retaining the other member of the pair. Photons in the return signal are checked for telltale signatures of entanglement, allowing photons from the noisy environmental background to be discarded. This can greatly improve the radar signal-to-noise in certain situations.
To date, quantum illumination has only been explored in the laboratory. The Government of Canada, under the Department of National Defence's All Domain Situational Awareness (ADSA) Science & Technology program, is investing $2.7 million to expedite its use in the field.
"This project will allow us to develop the technology to help move quantum radar from the lab to the field," said Baugh. "It could change the way we think about national security."

Yes. I have a message. I cannot edit or remove it.

You've had "multiple death threats" because of your participation on ATS?
Funny that, I have dozens over the last two decades too. They don't mean much in the real world thankfully, as long as you have proper security when going to public outings.
