Multipartite entanglement detection in bosons

Abstract

We propose a simple quantum network to detect multipartite entangled states of bosons, and show how to implement this network for neutral atoms stored in an optical lattice. We investigate the special properties of cluster states, multipartite entangled states and superpositions of distinct macroscopic quantum states that can be identified by the network.
