This is a very interesting method to obtain images of objects that are outside
the visual range of a camera.

A camera took this image of a toy soldier without collecting any light that had gone near it. Instead it recorded photons with a quantum link to others that did bounce off it

Ok, so let me get this straight... you have a photon source aimed at a splitter. Call the splitter point 'A'. Then you have a Photon detector and an object that are both equidistant from point 'A' but arranged in a way that the photon detector has no way of visually 'seeing' the detected object... an optical diode if you will. Because of something weird that happens on a Quantum level, if a photon is absorbed at the object, the photon that is equidistant at the Photon receiver is disrupted because it is in "Quantum Sync" with the absorbed photon and detected?
Strange but cool!
