Multiple-photon resolving fiber-loop detector
arXiv:quant-ph/0303032 · doi:10.1103/PhysRevA.67.061801
Abstract
We show first reconstructions of the photon-number distribution obtained with a multi-channel fiber-loop detector. Apart from analyzing the statistics of light pulses this device can serve as a sophisticated postselection device for experiments in quantum optics and quantum information. We quantify its efficiency by means of the Fisher information and compare it to the efficiency of the ideal photodetector.
