Contribution

It provides a realistic experimental framework for implementing the Dicke model and generating entanglement via subradiant states in ion-cavity QED.

Findings

Ideal subradiance and superradiance can be observed under realistic conditions.

An experimental protocol for entanglement generation exploiting subradiant states is proposed.

Conditions for optimal entanglement are achievable with current technology.

Abstract

We investigate realistic experimental conditions under which the collective Dicke model can be implemented in 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.
