Generation of Multicavity Entangled States with a Single Three-Level Atom

Abstract

A simple scheme is proposed for the generation of maximally entangled states for several separated cavities, in which each cavity is in a one-photon state or in the vacuum state. In the scheme a laddertype three-level atom is sent through the cavities and additional classical fields. The whole system finally evolves into a state, which is given by the product of the highly entangled field state with an atomic state.
