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

Temporal ghost imaging
TL;DR: In this paper, a simple experimental setup for temporal ghost imaging that can be implemented even in the undergraduate physics laboratory is presented. But the experimental setup is limited to the case where the object is not a spatial mask but a temporally varying modulation of the light.

Experimental observation of aberration cancellation in entangled two-photon beams
TL;DR: It is shown that using two-photon correlation imaging and a suitably prepared source of photon pairs, antisymmetric optical aberrations of an imaging system can be cancelled out.

Ghost Imaging with High Visibility Using Classical Light Source
TL;DR: In this article, the authors demonstrate a novel ghost imaging experiment utilizing a classical light source, capable of resolving objects with a high visibility, which could have applications in remote sensing. But the experimental results show that their scheme can indeed realize ghost imaging with high visibility for a relatively complicated object composed of three nearellipse-shaped holes with different dimensions.

Metasurface-Assisted Quantum Ghost Discrimination of Polarization Objects
TL;DR: In this paper, the authors developed a metasurface-assisted ghost imaging for non-local discrimination between a set of polarization objects, which can find applications for real-time and low-light imaging across diverse spectral regions in dynamic environments.

Remote temporal wavepacket narrowing.
TL;DR: This work experimentally demonstrates the effect of remote temporal wavepacket narrowing of a heralded single photon produced via spontaneous parametric down-conversion and investigates optimal photon pair source characteristics to minimize heralded wavepackets width.
