Continuous-variable Gaussian analog of cluster states

Year: 2006

Type: article

Abstract: We present a continuous-variable (CV) Gaussian analog of cluster states, a new class of CV multipartite entangled states that can be generated from squeezing and quantum nondemolition coupling ${H}_{I}=\ensuremath{\hbar}\ensuremath{\chi}{X}_{A}{X}_{B}$. The entanglement properties of these states are studied in terms of classical communication and local operations. The graph states as general forms of the cluster states are presented. A chain for a one-dimensional example of cluster states can be readily experimentally produced only with squeezed light and beam splitters.
