General Model of Photon-Pair Detection with an Image Sensor

Abstract

We develop an analytic model that relates intensity correlation measurements performed by an image sensor to the properties of photon pairs illuminating it. Experiments using an effective single-photon counting camera, a linear electron-multiplying charge-coupled device camera, and a standard CCD camera confirm the model. The results open the field of quantum optical sensing using conventional detectors.

Optimizing the signal-to-noise ratio of biphoton distribution measurements

“…This form of the "click" probability allows the simple insertion of the quantum efficiency as in Eqs. (4) [25]. Applying this concept to the EMCCD camera requires the probability of getting a gray level above threshold to scale as…”

Quantum image distillation

“…However, this result is only valid for r 1 ‰ r 2 . As described in Appendix H of the supplementary document of [27], xIprq 2 y can be written as:…”

Ghost network analyzer

“…Various types of sources have been employed in both quantum and classical ghost imaging so far. In quantum ghost imaging, the quantum source provides entangled-photon pairs with strong spatial correlations via parametric down-conversion (PDC) [10][11][12][13][14] or correlated atom pairs via Bose-Einstein condensates [15]. In classical ghost imaging, the beams with classical correlations are generated by the thermal/pseudothermal light sources [16][17][18][19][20][21][22].…”
