An Element of Physical Reality on the Choice of Measurement Basis



David Song


It is shown that the choice of measurement basis where entangled systems are measured in cannot be local elements of reality. Two distant parties share maximally entangled states and chosen bases between Z and X with P=1/2 are used to perform measurements at each end. Following the similar logical structure to Hardy's nonlocality without inequalities for two particles, we show that elements of physical reality for the choice of measurement basis with respect to the outcome of entangled states cannot be local.
