The late Carl Sagan once said, “Extraordinary claims require extraordinary evidence.”
And scientists in China are reportedly developing a new quantum radar technology that could detect stealth planes by creating a small electromagnetic storm, according to a study recently published in the journal Journal of Radars, a China-based peer-reviewed publication, reports on the South china morning post.
However, this is not the first time researchers from China have made big claims about a working quantum radar, and many experts from other countries deny the feasibility of such devices, suggesting that this could be a technological bluff.
So take this with a grain of salt.
China Makes Big Claims About Working “Quantum Radar”
Traditional radars have a fixed or rotating dish, but the quantum radar design is more like a cannon and accelerates electrons to almost the speed of light. As soon as they pass a coiled tube exposed to strong magnetic fields, the electrons could create a vortex of microwaves, which, according to the report, swirls forward like a horizontal tornado. If completed successfully, the novel quantum radar system would outperform any radar system in the past, but that’s still a big “if,” said Zhang Chao and his team from Tsinghua University at the Aerospace Engineering College. But the potential benefits are well worth the hard work, according to the team of scientists. The “better the stealth technology, the higher the gain” of the quantum radar system, they added SCMP Report.
However, the fundamental particles used in this man-made electromagnetic storm would have strange properties, the researchers added. In the study, each particle maintained a spiral impulse that did not decrease over time and distance. Einstein’s work states that this is not physically possible, but the researchers stressed that quantum mechanics bypasses the theories of the late physicist and allows the system to spot targets that conventional radar would never see. And that works not only from a great distance, but also in bad weather.
‘Quantum Radar’ could actually be a bluff from China
If the system really works and is deployed in contested airspace, it could be a significant asset. Even today, most aircraft cannot hide their signature from the radar because they reflect electromagnetic waves. Stealth aircraft such as the US F-22 Raptor or F-35 fighter aircraft absorb a large part of the radar waves via a special coating material that, in combination with minimal right angles in the outer structure of the vehicle, sends a radar signal to an object the size of a Reduce baseballs. Stealth technology like this has proven to be a distinct advantage over other nations’ air forces, which rely primarily on 20th century jet fighters with no stealth capabilities.
In recent years, however, the sensitivity of military radar has increased, possibly high enough to detect even stealth aircraft. But in return, novel metamaterials have further improved camouflage capabilities and reduced the visibility of aircraft even further. And as stealth technology continues to improve, some believe it will exceed the detection capabilities of any radar. For this reason, weapons engineers suggested quantum radar as a possible solution to the detection dilemma more than a decade ago. Military scientists in China said they were testing a prototype quantum radar back in 2016, but this has been fiercely denied by legitimate scientific authorities. A report published in Science magazine argued last year that quantum radar may never be used for long-range applications such as stealth aircraft tracking, as experiments have found critical errors – one of which suggests such devices only operate near absolute zero – that are apparently well below the temperature of the Chinese Heaven lie. “I am convinced that if [China] announced that their quantum radar was not working, “said Fabrice Boust, radar specialist and physicist at ONERA, France, in 2020 Science magazine Report. “But they knew they would get a response.” Well, if China wants that, then it works.
