Abstract

We develop a comprehensive approach to analyzing the continuous output of photon detectors. It uses principle component analysis to extract information available from such detectors, followed by a novel parameterized photon-number resolving detector tomography approach that is robust to noise. We further study the role of prior photon number distributions and propose a measure of quantifying the confidence of a detector's photon-number-resolving capability. We use our measure to compare different detectors in use.
