China's Quantum Radar Could Detect Stealth Planes, Missiles (popsci.com)

Posted by BeauHD on from the eastern-arsenal dept.

hackingbear shares a report from Popular Science: China Electronics Technology Group Corporation (CETC), China's foremost military electronics company, announced that its groundbreaking quantum radar has achieved capability of tracking high altitude objects, likely by increasing the coherence time entangled photons. CETC envisions that its quantum radar will be used in the stratosphere to track objects in "the upper atmosphere and beyond" (including space). Quantum can identify the position, radar cross section, speed, direction and even "observe" on the composition of the target such as differentiating between an actual nuclear warhead against inflatable decoys. [...] Importantly, attempts to spoof the quantum radar would be easily noticed since any attempt to alter or duplicate the entangled photons would be detected by the radar. The news is an important illustration of a larger trend of Chinese advancement in the new, crucial area of quantum research. Other notable projects in China's quantum technology include the Micius satellite, and advances by Alibaba and the Chinese University of Science and Technology in a world record of entangling 18 photons (a quantum supercomputer would require about 50 entangled photons), such that China arguably leads the world in quantum technologies.

    We should implement Blockchain RADAR immediately as a response to this newfangled Quantum RADAR.

      I know your idea sounds ridiculous on the surface, but if you use deep learning, you can put it in a div with Javascript. You couldn't before, but WebAssembly makes it possible. That's the advantage of Chinese hypertext.

    You never let your enemy know your position.

    Just tell them your velocity.

    As opposed to the other classic military blunder: “Never go in against a Sicilian, when death is on the line!”

    (think pre-launch even)

    You mean by following the enemy president's twitter account?

    A spoon? LOL try a shovel.. nay a truckload.

    I mean this is the same country that alters the AQI measurements and banned Winnie the Pooh.

    So to think that they have anything remotely capable of what they claim, without, you know PROOF (not just a research paper) if laughable.

    You'd ban someone too if you knew he had a habit of running off into the woods without any pants, with a baby pig, while carrying a jar of honey.
