One of their possible ideas is based on a method going by the evocative name of "quantum ghost imaging" or Zou-Wang-Mandel ...

Using these photon pairs, quantum imaging with unprecedented resolution and field of view can be achieved by combining quantum ghost imaging and all-optical scanning. Disclaimer: AAAS and EurekAlert!

For decades, quantum imaging has promised sharper images and greater light sensitivity than classical methods by exploiting the unique properties of quantum light, such as photon entanglement.
