    "abstract": "We investigate multipartite entanglement in relation to the theoretical\nprocess of quantum state exchange. In particular, we consider such entanglement\nfor a certain pure state involving two groups of N trapped atoms. The state,\nwhich can be produced via quantum state exchange, is analogous to the\nsteady-state intracavity state of the subthreshold optical nondegenerate\nparametric amplifier. We show that, first, it possesses some 2N-way\nentanglement. Second, we place a lower bound on the amount of such entanglement\nin the state using a novel measure called the entanglement of minimum bipartite\nentropy.",
