TLDR
In this article, a two-photon optical imaging experiment was performed based on the quantum nature of the signal and idler photon pairs produced in spontaneous parametric down-conversion, where an aperture placed in front of a fixed detector is illuminated by the signal beam through a convex lens.Abstract:
A two-photon optical imaging experiment was performed based on the quantum nature of the signal and idler photon pairs produced in spontaneous parametric down-conversion. An aperture placed in front of a fixed detector is illuminated by the signal beam through a convex lens. A sharp magnified image of the aperture is found in the coincidence counting rate when a mobile detector is scanned in the transverse plane of the idler beam at a specific distance in relation to the lens.read more

Ghost-imaging experiment by measuring reflected photons
TL;DR: In this article, a CCD array is placed facing a chaotic light source and gated by a photon counting detector that simply counts all randomly scattered and reflected photons from an object, and a ''ghost'' image of the object is then observed in the gated CCD.

Ghost imaging through turbulent atmosphere
TL;DR: Based on the extended Huygens-Fresnel integral, an analytical imaging formula is obtained that can be viewed as the convolution of the original object and a point-spread function (PSF).

Single-pixel imaging 12 years on: a review
TL;DR: This review considers the development of single-pixel cameras from the seminal work of Duarte et al. up to the present state of the art, covering the variety of hardware configurations, design of mask patterns and the associated reconstruction algorithms, many of which relate to the field of compressed sensing and, more recently, machine learning.

TL;DR: This work demonstrates the contrast enhancement of images within a ghost-imaging system by use of nonlocal phase filters and shows a violation of a Bell-type inequality for an OAM subspace, thereby unambiguously revealing the quantum nature of this arrangement.

TL;DR: In this paper, the authors investigate experimentally fundamental properties of coherent ghost imaging using spatially incoherent beams generated from a pseudo-thermal source and show a complementarity between ghost diffraction and ordinary diffraction patterns.
