Bipartite entanglement of multipartite coherent states using quantum network of beam splitters

摘要

We investigate the generation of multipartite entangled SU(k+1) coherentstates using a quantum network involving a sequence of k beam splitters. Weparticularly investigate the entanglement in multipartite SU(2) coherent states(k = 1). We employ the concurrence as measure of the degree of bipartiteentanglement.
