This article on New Scientist has me puzzled:
http://ift.tt/1udab2F
TL;DR; A pair of photons are entangled. On set is fired at a stencil, while the other is fired at the camera. The result is a picture created by photons that never interacted with the stencil.
I don't understand how this can work. I mean, I get the idea that because the photons are entangled they share properties, but how does this lead to the forming of a coherent image? This image can't be the result of a single entangled pair of photons can it? I mean, in order for the camera to produce the image, there must have been many millions of photons striking the CCD?
The article is thin on detail, but I cannot imagine how it was possible to form this image. At a minimum, each pixel in the image must correspond to a photon striking the CCD (as I understand it). Did they entangle and send an entire beam of photons big enough to illuminate the entire stencil?
Can someone please help me understand the set up here?
