The analogy between two-level atoms and spins is used to show that Rydberg
atoms provide a new medium through which Bell's inequalities may be
studied. The low-efficiency particle detectors that have been used in
experiments to test Bell's inequalities are replaced by nearly 100%
efficient state-selective ionizers in Rydberg-atom experiments. Two
methods for producing correlated states of pairs of atoms are discussed.
Each method can be used to create correlated states of more than two atoms.
A Bell inequality for a three-atom system is considered and compared with
quantum-mechanical predictions. A violation of the inequality for the
three-particle system is predicted.
