A quantum-technology military arms race between the U.S. and China is on.  Given China’s ‘impressive effort to turbocharge quantum research’ in military-applied quantum technology and the U.S.’ quiet but known efforts, the gap between these powerful nations is closing.  Detecting stealth aircraft and weaponry, enhanced navigation capabilities, and ultra-sensitive magnetic anomaly sensors, are three areas where quantum science is being studied and applied to military uses.

Using entangled photons to detect stealth aircraft is a focus of study by China.
