alternative_right quotes a report from the New York Post: The CIA used a futuristic new tool called "Ghost Murmur" to find and rescue the second American airman who was shot down in southern Iran, The Post has learned. The secret technology uses long-range quantum magnetometry to find the electromagnetic fingerprint of a human heartbeat and pairs the data with artificial intelligence software to isolate the signature from background noise, two sources close to the breakthrough said. It was the tool's first use in the field by the spy agency -- and was alluded to Monday afternoon by President Trump and CIA Director John Ratcliffe at a White House briefing. "It's like hearing a voice in a stadium, except the stadium is a thousand square miles of desert," a source briefed on the program told The Post. "In the right conditions, if your heart is beating, we will find you." The relatively barren landscape made for "an ideal first operational use" of Ghost Murmur, the first source noted. "Normally this signal is so weak that it can only be measured in a hospital setting with sensors pressed nearly against the chest," the source said. "But advances in a field known as quantum magnetometry -- specifically sensors built around microscopic defects in synthetic diamonds -- have apparently made it possible to detect these signals at dramatically greater distances." "The capability is not omniscient. It works best in remote, low-clutter environments and requires significant processing time," this person added.Read more of this story at Slashdot.
