TL;DR: It is shown that modern electron-multiplying charge-coupled device cameras can measure correlations in both position and momentum across a multi-pixel field of view and demonstrate Einstein–Podolsky–Rosen type correlations by more than two orders of magnitude.

TL;DR: In this paper, a camera-based ghost imaging system where the correlated photons have significantly different wavelengths is described. But the system is based on parametric down-conversion and the image data are recorded from the coincidently detected, position-correlated, visible photons at a wavelength of 460nm using a highly efficient, low-noise, photon counting camera.

TL;DR: In this paper, a time-gated camera was used to record the single-photon events across the full scene, and high contrast images were obtained in either the image plane or the far field of the photon pair source, taking advantage of the Einstein-Podolsky-Rosen-like correlations in position and momentum of photon pairs.

TL;DR: In this paper, a time-gated camera was used to record the single-photon events across the full scene and obtained high contrast images, 90% in either the image plane or the far-field of the photon pair source, taking advantage of the EPR-like correlations in position and momentum of photon pairs.

TL;DR: In this paper, the use of the transverse spatial degrees of freedom of photons propagating in the paraxial approximation for continuous-variable information processing is discussed, and a set of continuous quantum logic gates which allow for universal quantum computation are implemented.
