摘要：

A pair of rigorously correlated photons (biphotons) from parametric down conversion makes it possible to use them for measuring the absolute value of the quantum efficiency of the optical detectors, both in photon counting and in analog regimes, that does not use any calibrated standard light sources. Using this method the quantum efficiency of EG&G avalanche photodetectors was determined.
