Here, we demonstrate high-efficiency PNR detectors using a parallel superconducting nanowire single-photon-detector (P-SNSPD) architecture that does not suffer from crosstalk between the pixels and that is free of latching. The behavior of the detector is modeled and used to predict the possible outcomes given a certain number of incoming photons. We apply our model to a four-pixel P-SNSPD with a system detection efficiency of 92.5%. We also demonstrate how this detector allows reconstructing the photonnumber statistics of a coherent source of light, which paves the way towards the characterization of the photon statistics of other types of light source using a single detector.</p> Dewey 500.2 European Commission Applications and Hardware for Photonic Quantum Information Processing 956071 AppQInfo EU H2020 35 Groupe de physique appliquée 135 false 1404 Groupe Thew 1408 Groupe Zbinden Physical review applied 19 6 0571a883-8a19-40c2-997c-a530b610b56b Article (Published version) Public Article-scientifique-from-crossref.pdf 1981468 application/pdf ace3d5ac30ae5630b255389343d9489df62a527966df886167bbc8939418562b openAccess Faculté des sciences / Section de physique / Groupe de physique appliquée
