Abstract

An approach to the measurement induced geometric phase based on the de Broglie–Bohm hidden-variable model is developed. The analysis involves an evolving geometric phase connecting the initial and final states of an individual experimental run. As an illustration the geometric phase produced by a cyclic sequence of spin-12 filtering experiments is considered. It is argued, in this case, that the evolving geometric phase can be made close to the Samuel-Bhandari phase.
