Abstract
Previous work on Bell's inequality realized in the laboratory have used entangled photons. Here we describe how entangled atoms can violate Bell's inequalities, and how these violations can be measured with a very high detection efficiency. To prepare the atoms in an entangled state they are placed at fixed positions inside a cavity. We first discuss a simple scheme based on two-level atoms, followed by a scheme using three-level atoms, which should be easier to implement experimentally using present technology.
