Abstract
A new approach is proposed to the calibration of photodetectors and the det ermination of the absolute value of the quantum efficiency of photon-counti ng photomultipliers using entangled-photon pairs. It is based on a new sing le-photodetector technique and a special modulation of the entangled-photon flux. The absolute values of the quantum efficiency have been determined f or several photon-counting photomultipliers.
