Abstract :
Correlated photons can be used to measure the quantum efficiency of photon counting photodetectors without ties to any externally calibrated standards. We present a study of measurement systematics aimed at reducing the measurement uncertainties to the 0.1% level, and developing a robust measurement protocol
