    "abstract": "We use techniques for lower bounds on communication to derive necessary\nconditions in terms of detector efficiency or amount of super-luminal\ncommunication for being able to reproduce with classical local hidden-variable\ntheories the quantum correlations occurring in EPR-type experiments in the\npresence of noise. We apply our method to an example involving n parties\nsharing a GHZ-type state on which they carry out measurements and show that for\nlocal-hidden variable theories, the amount of super-luminal classical\ncommunication c and the detector efficiency eta are constrained by eta 2^(-c/n)\n= O(n^(-1/6)) even for constant general error probability epsilon = O(1).",
