Positive Operator-Valued Measure reconstruction of a beam-splitter tree based photon-number-resolving detector
arXiv:1412.8630 · doi:10.1364/OL.40.001548
Abstract
Here we present a reconstruction of the Positive Operator-Value Measurement of a photon-number-resolving detector comprised of three 50:50 beamsplitters in a tree configuration, terminated with four single-photon avalanche detectors. The four detectors' outputs are processed by an electronic board that discriminates detected photon number states from 0 to 4 and implements a "smart counting" routine to compensate for dead time issues at high count rates.
