We investigate realistic experimental conditions under which the collective Dicke model can be implemented in the ion-cavity QED context. We show how ideal subradiance and superradiance can be observed and we propose an experiment to generate entanglement exploiting the existence of the subradiant state. We explore the conditions to achieve optimal entanglement generation and we show that they are reachable with current experimental technology. ©2009 The American Physical Society
