Quantum ghost imaging can achieve unprecedented sensitivity by detecting not just the extremely small amount of light straying off a dim target, but also its interactions with other light in the surrounding environment to obtain more information than traditional methods.
You know how madly futuristic this would sound to someone from 1967, right? Or even 1992 I'd wager. Oh, hell, even now.
Presumably this will be followed by another leap in stealth technology, but what?
