Entangled-photon compressive ghost imaging

Here the last paper of the year: Entangled-photon compressive ghost imaging by Petros Zerom, Kam Wai Clifford Chan, John C. Howell, and Robert W. Boyd. The abstract reads:
We have experimentally demonstrated high-resolution compressive ghost imaging at the single-photon level using entangled photons produced by a spontaneous parametric down-conversion source and using single-pixel detectors. For a given mean-squared error, the number of photons needed to reconstruct a two-dimensional image is found to be much smaller than that in quantum ghost imaging experiments employing a raster scan. This procedure not only shortens the data acquisition time, but also suggests a more economical use of photons for low-light-level and quantum image formation.

Since it is behind a paywall, the following presentations might provide some additional insight:
