Abstract
The authors propose a new scheme for measuring the quantum efficiency of photon counting detectors by using correlated photons. The scheme consists in measuring the polarization state of one member of a correlated pair after a 90deg polarization rotation conditioned to the detection of the other correlated photon after polarization selection. The authors present experimental results obtained with this scheme compared with traditional correlated photon calibration
