Multipartite entangled coherent states

Abstract

We propose a scheme for generating multipartite entangled coherent states via entanglement swapping, with an example of a physical realization in ion traps. Bipartite entanglement of these multipartite states is quantified by the concurrence. We also use the $N$--tangle to compute multipartite entanglement for certain systems. Finally we establish that these results for entanglement can be applied to more general multipartite entangled nonorthogonal states.

7 pages, two figures. We added more detail discussions on the generation of multipartite entangled coherent states and multipartite entangelement
