    "abstract": "By limiting the resolution of quantum measurements, the measurement induced\nchanges of the quantum state can be reduced, permitting subsequent measurements\nof variables that do not commute with the initially measured property. It is\nthen possible to experimentally determine correlations between non-commuting\nvariables. The application of this method to the polarization statistics of\nentangled photon pairs reveals that negative conditional probabilities between\nnon-orthogonal polarization components are responsible for the violation of\nBell\u0027s inequalities. Such negative probabilities can also be observed in finite\nresolution measurements of the polarization of a single photon. The violation\nof Bell\u0027s inequalities therefore originates from local properties of the\nquantum statistics of single photon polarization.",
