Abstract

Quantum imaging experiments rely on the detection of correlated photon-pairs. Due to experimental configuration the detected strength of correlations can be larger than a single detector pixel and as such may not be collected by a simple algorithm. Here we show the improvement offered by integrating over the correlation peak to enhance the pixel-by-pixel AND operation and demonstrate an enhancement of over approximately 43%. This technique to collect an increased proportion of correlated photon-pairs can be used to improve the output of quantum enhanced imaging techniques for use in low-light imaging systems to improve noise rejection, image contrast, and image resolution.
