Can the choices of measurement basis for entangled quantum systems be random
Year: 2004
Type: preprint
Abstract: It is shown that, with respect to the outcomes of two entangled quantum systems, the choices of measurement basis cannot be independent from each other. Two parties share maximally entangled states and bases chosen between $Z$ and $X$ with $P=1/2$ are used to perform measurements at each end. With the assumption that an element of physical reality for the choice made at one end is not a function of the outcome of an entangled state at the other end, we derive a contradiction to this assumption and show that elements of physical reality for the choice of measurement basis at each end cannot be independent from each other.
