    "abstract": "An analysis of detector-efficiency in many-site Clauser-Horne inequalities is\npresented, for the case of perfect visibility. It is shown that there is a\nviolation of the presented n-site Clauser-Horne inequalities if and only if the\nefficiency is greater than n/(2n-1). Thus, for a two-site two-setting\nexperiment there are no quantum-mechanical predictions that violate local\nrealism unless the efficiency is greater than 2/3. Secondly, there are n-site\nexperiments for which the quantum-mechanical predictions violate local realism\nwhenever the efficiency exceeds 1/2.",
