CIA used "long-range quantum magnetometry" called "Ghost Murmur" in Iran (nypost.com)

The article says the CIA used a previously untested system called “Ghost Murmur,” described as long-range quantum magnetometry that can detect a human heartbeat’s electromagnetic signature and use AI to distinguish it from background noise. It reports the tool was deployed during a two-day search for a downed U.S. airman in southern Iran and helped confirm his location in a remote mountain crevice. The piece adds that the technology was developed by Lockheed Martin’s Skunk Works and has been tested on helicopters, while noting its broader potential uses are unclear.
