Abstract
It is shown that the deflection of an atom de Broglie wave at a nonresonant weak cavity field mode can yield a pure entangled quantum state in which discernable atomic beams are entangled to photon number states of the field and to internal states of the atom. The proposed experimental scheme is shown to be applicable for quantum nondemolition measurement of the photon statistics, and for quantum state engineering and reconstruction experiments.
