Abstract
Disclosed is an apparatus for single-pixel imaging using quantum light, the apparatus including: a light source which generates a photon pair through spontaneously parametric down conversion of a non-linear crystal and splits the photon pair into an idler photon of first polarized light and a signal photon of second polarized light; a signal processing unit which aligns the signal photon with the first polarized light and modulates the signal photon with a pattern of a spatial light modulator, and sends the modulated signal photon to a target; and a signal detecting unit which simultaneously measures signal photons collected after an interaction of the idler photon and the target to obtain an image.
