Abstract
We show that the recent proposal by Hardy and Jordan for a test of loc al realism without the use of Bell inequalities can be implemented in two-photon coincidence measurements with linear polarizers, when the p roton pairs are produced by parametric downconversion. If the probabil ities measured with real detectors are proportional to the correspondi ng probabilities determined with ideal detectors, this method does not depend on the use of detectors with high or even known quantum effici encies.
