You don't even need to capture a photon coming from the object.

Shoot a red laser at a couple of non-linear crystals to split the photons into a red/infrared entangled pair. Now, send the infrared ones through the object and into the other crystal while you divert the red ones to a screen without touching the object. As you can no longer determine which infrared photon belongs to what entangled pair the information they ones had is now contained in the red photons instead - and an image of the object appears on the screen.

Who the hell needs magic when there's quantum physics.

That's not quite what happens. Based on your description information about an object could travel faster than light.

You send light from cristal A to the object and then on to cristal B. You then construct the image using light from both cristals. The specific spookiness is only apparent when you try and track an individual photon.
