Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), the Vienna Center for Quantum Science and Technology (VCQ), and the University of Vienna
have developed a new quantum imaging technique in which the image has been obtained without ever detecting the light that was used to illuminate the imaged object.
Their sketch of a cat was generated with photons that have never touched the object, instead using entangled pairs of photons and discarding the photons that have interacted with the sketch. The researchers are confident that their new imaging concept is very versatile and could even find applications where low light imaging is crucial, in fields such as biological or medical imaging.

You could of course sent your photons to the moon, but you'd then have to have the photons to return to earth, so that you can then on earth erase the information on whether the photons actually went to moon. Without erasing that information, you'll not get the image. So no remote sensing without return of light, sorry.

oh. dam. there's always a catch.
