Abstract
We present a method of using a high-flux entangled photon-pair source to improve the signal-to-noise ratio of a single-pixel imaging system. Sensing with single-photon counting detectors will often suffer from measurement noise due to any background light levels. Using a single detector enables a high efficiency of detection and when paired with a variable transmission mask enables full images to be captured. The heralding photon from the source acts as a temporal reference, allowing the signal photons to be distinguished from background noise. This heralding method is key to understanding how quantum measurements can produce higher contrast images than their classical equivalent.
