China Says It Has Developed a Quantum Radar That Can See Stealth Aircraft (digitaltrends.com)

An anonymous reader quotes a report from Digital Trends: At a recent air show in the city of Zhuhai, state-owned Chinese defense giant China Electronics Technology Group Corporation displayed what it claims to be a quantum radar that's able to detect even the stealthiest of stealth aircraft. The company claims to have been working on the technology for years, and to have tested it for the first time in 2015. In principle, a quantum radar functions like a regular radar -- only that instead of sending out a single beam of electromagnetic energy, it uses two split streams of entangled photons. Only one of these beams is sent out, but due to a quirk of quantum physics both streams will display the same changes, despite being potentially miles apart. As a result, by looking at the stream which remains back home it's possible to work out what has happened to the other beam. According to a brochure from the China Electronics Technology Group Corporation, the new quantum radar could "solve the traditional bottleneck [of] detection of low observable target detection, survival under electronic warfare conditions, [and] platform load limitations."

    Dwave also has developed a 1000 qubit quantum computer. And Musk is building a hyperloop tunnel system and a Mars colony. And soon we will have AI and self-driving cars. We live in exciting times, my friends.

    It detects the plane if you don't look at the radar screen

    China both has and does not have a quantum radar.
    They won't know until they open the box.

    We've got quantum BLOCKCHAIN radar. It not only detects stealthy aircraft, it can detect aircraft you don't even have but wish you did.
