Query: A quantum loophole to Bell nonlocality   We argue that the conclusion of Bell theorem, namely, that there must be
spatial non-local correlations in certain experimental situations, does not
apply to typical individual measurements performed on entangled EPR pairs. Our
claim is based on three points, (i) on the notion of quantum {\it complete
measurements}; (ii) on Bell results on local yet distant measurements; and
(iii) on the fact that perfect simultaneity is banned by the quantum mechanics.
We show that quantum mechanics indicates that, while the measurements of the
pair members are indeed space-like separated, the pair measurement is actually
a sequence of two complete measurements, the first one terminating the
entanglement and, therefore, the second one becoming unrelated to the initial
preparation of the entangled pair. The outstanding feature of these
measurements is that neither of them violates the principle of locality. We
discuss that the present measurement viewpoint appears to run contrary to the
usual interpretation of "superposition" of states with its concomitant
"collapse" on measurement.
