Cavity Decay

In this paper, we present a scheme to prepare the W state and the GHZ state of many atomic ensembles based on the dynamics of the atomic system of a single control atom and an atomic ensemble dispersively coupling with a cavity, where the control atom is illuminated by a highly detuned auxiliary classical field at the same time. The dynamics of the atomic system can be described by an effective Jaynes–Cummings model (JCM) with the atomic ensemble as the bosonic mode. The preparation of the entangled states is deterministic. Because the cavity is always in the vacuum state during the whole evolution process, our scheme is less sensitive to the cavity decay.

Cavity Decay

A scheme of quantum concentration for unknown atomic entangled states via cavity QED is proposed. During the preparation and the joint measurement of quantum states, the cavity is only virtually excited; thus, the scheme is insensitive to the cavity field states and the cavity decay. In the meanwhile, our setup also provides a demonstration of a quantum repeater in cavity QED in principle.
