Abstract
Recently Hardy has exhibited a striking new violation of local realism that occurs in a pair of interferometers that have been interconnected so that knowledge about the path chosen by a particle in one interferometer conveys some information about the path or paths chosen by the particle in the other interferometer. It has been demonstrated that particle annihilation and a two-photon interference effect can be exploited to give rise to this local realism violation. Here we show that in the case of fermion interferometers the Pauli exclusion principle can be exploited to give rise to this effect.Keywords
