TLDR
This work shows that the resolution of quantum ghost imaging systems can be further degraded by reducing the strength of the spatial correlations inherent in the downconversion process.Abstract:
Quantum ghost imaging uses photon pairs produced from parametric downconversion to enable an alternative method of image acquisition. Information from either one of the photons does not yield an image, but an image can be obtained by harnessing the correlations between them. Here we present an examination of the resolution limits of such ghost imaging systems. In both conventional imaging and quantum ghost imaging the resolution of the image is limited by the point-spread function of the optics associated with the spatially resolving detector. However, whereas in conventional imaging systems the resolution is limited only by this point spread function, in ghost imaging we show that the resolution can be further degraded by reducing the strength of the spatial correlations inherent in the downconversion process.read more

Imaging with quantum states of light
TL;DR: Using quantum states of light for imaging both reveals quantum phenomena and enables new protocols that result in images that surpass classical limitations as discussed by the authors, such as image contrast, resolution enhancement that exceeds the classical limit and acquisition of sub-shot-noise phase or amplitude images.

Microscopy with undetected photons in the mid-infrared.
TL;DR: It is experimentally shown how nonlinear interferometry with entangled light can provide a powerful tool for mid-IR microscopy while only requiring near-IR detection with a silicon-based camera.
