Brian W + 78 BW November 16, 2018 Defence giant China Electronics Technology Group Corporation claims to have created a quantum radar that can detect stealth fighter jets from great distances and see through the radar jamming used to hide warplanes. A company displayed the prototype at the Zhuhai air show last week. Stealth aircraft avoid detection by redirecting most of a radar system’s radio waves, which usually reflect off their surface and reveal their location. The mobile quantum radar is able to spot and track targets more than 62 miles away in the daylight and over the sea, according to Chinese media. A quantum radar can spot objects that are invisible to traditional radio wave-based systems by a principle called quantum entanglement, in which two photons form a connected pair even over great distances. The system would send out one of the photons, while the other in the pair would stay behind. According to the researchers, it could vastly improve the accuracy in environments with a lot of background noise. This news caused a lot of skepticism because only representatives of Chinese media could attend this demonstration. https://www.techspot.com/news/77448-china-claims-has-developed-quantum-radar-can-detect.html Quote Share this post Link to post Share on other sites
Adam Varga + 123 AV November 16, 2018 China is talking about this radar for a long time. I thought that this kind of a "news" should be a top secret. This way is sounds more like a propaganda. Quote Share this post Link to post Share on other sites
BlackTortoise + 103 CM November 16, 2018 Agree, in military terms you dont talk about this stuff. These are black programs. So they got my skepticism too. I'm going to take their claims with a grain of salt. But if they really have it now then I can only imagine what the Pentagon has developed. Quote Share this post Link to post Share on other sites
DA? + 301 jh November 16, 2018 Probably not as once you entangle particles its really easy to undo it and sending them through the atmosphere unprotected seems not likely. But the Chinese have got entangled particles in satellites for experimental communication. Although just a FM radar sees stealth aircraft, not accurately but within a range of hundreds of meters.

Vlad Kovalenko + 115 VK November 16, 2018 Canada announced this April that it would develop a quantum radar system. The project is funded by Canada's Department of National Defense and is expected to cost $2.7 million. https://gizmodo.com/canadas-defense-department-is-funding-a-quantum-radar-s-1825470931 Quote Share this post Link to post Share on other sites
