Résumé : The average communication necessary to simulate classically a violation of a Bell inequality was studied and found to be proportional to the degree of violation of the inequality. To each set of correlation is associated an optimal inequality for which that communication is also sufficient to reproduce the entire set of correlations. The key ingredient was to compare the amount of violation of Bell inequalities not only with the maximum value they take on local deterministic strategies, but also on nonlocal ones that necessitate some communication to be implemented.
