    "abstract": "It is shown that two observers have mutually commuting observables if they\nare able to prepare in each subsector of their common state space some state\nexhibiting no mutual correlations. This result establishes a heretofore missing\nlink between statistical and locality (commensurability) properties of the\nobservables of spacelike separated observers in relativistic quantum physics,\nenvisaged four decades ago by Haag and Kastler. It is based on a discussion of\ncoincidence experiments and suggests a physically meaningful quantitative\nmeasure of possible violations of Einstein causality.",
