Abstract
We propose a coincidence measurement scheme of combining on-off and photon number resolving (PNR) detectors to discriminate the presence or absence of a low-reflectivity target using Gaussian entangled states in a strong thermal-noise environment. We show that, for coincidence counting, it is better to take the PNR detector on a signal mode and the on-off detector on an idler mode than to take the other way, which can exhibit a similar performance of the coincidence counting using PNR detectors.
