Summary:

- The article discusses the development of a new technology called "Quantum Radar" by researchers in China. Quantum radar is a novel sensing technology that uses quantum entanglement to detect objects with greater accuracy and sensitivity compared to traditional radar systems.

- The researchers claim that quantum radar can detect stealth aircraft and other low-observable targets that are difficult to detect with conventional radar. This technology has potential applications in national defense, air traffic control, and other areas where accurate detection of targets is crucial.

- The development of quantum radar is part of China's broader efforts to advance quantum technologies, which are seen as a critical area of strategic importance. The article highlights the competitive nature of the global race to achieve breakthroughs in quantum computing, quantum communication, and other quantum-based technologies.
