US EditionChina Claims Space Radar Can Track US Stealth Jets
China has achieved global leadership by mass-producing a four-channel single-photon detector that reduces noise by 90%, enabling detection of stealth jets like the F-22 and F-35.
- This month, reports said China has started mass production of the photon catcher, a four-channel ultra-low noise single-photon detector key for quantum radar and communications.
- The Quantum Information Engineering Technology Research Centre in Anhui province developed the device, reported last Friday by Science and Technology Daily, with China framing it as a step toward self-sufficiency.
- Using a four-channel design, the photon catcher reduces noise by 90%, scans multiple wavelengths simultaneously, isolates individual photons, and operates at cryogenic temperatures near-120°C.
- If fielded, the quantum radar node could let quantum radar track stealth fighters like the U.S. F-22 Raptor and F-35 Lightning II by adding data to layered sensor networks.
- Despite laboratory advances, experts point to integration and system-of-systems challenges, with Graham Hill, Heather Penney, and Edward Parker noting cryogenic cooling, fragile entanglement, and long signal integration times limit prototypes.

China Claims It Can Now ‘Detect’ F-22 Raptor Stealth Fighters
Key Points and Summary – Chinese researchers claim a major breakthrough with the mass production of a “single-photon detector,” the core component of a potential quantum radar system. This new technology would theoretically render stealth aircraft, including the U.S. F-22 and F-35, detectable by analyzing changes to individual photons that interact with an airframe. According to the claims, such a system would be immune to traditional jamming an…
China Is Developing A ‘World-First’ Quantum Radar To Track Stealth Jets Like The F-22
China has reportedly entered a new era in quantum technology with the mass production of ultra-sensitive photon detectors. According to the South China Morning Post (SCMP), Beijing calls this device the “world’s first ultra-low noise, four-channel single-photon detector”, a claim that, if accurate, could have vast implications in both communication and defense sectors. The breakthrough […] The post China Is Developing A ‘World-First’ Quantum Rad…
