Abstract
Hyper-Heisenberg scaling quantum imaging techniques that pass an idler photon of each entangled photon pair three times through an idler objective pair and pass a signal photon of each entangled photon pair at least once through a signal objective pair and use measurements of coincidence detection to yield a coincidence image with spatial resolution of about four times that of classical imaging.
