BIPARTITE ENTANGLEMENT OF MULTIPARTITE COHERENT STATES USING QUANTUM NETWORK OF BEAM SPLITTERS

摘要

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