Title: Experimental construction of optical multiqubit cluster states from Bell states

Abstract

Cluster states serve as the central physical resource for one-way quantum computing. We here present an experimental demonstration of the efficient cluster-state construction scheme proposed by Browne and Rudolph. In our experiment, three-photon cluster states with high purity are created from two Bell states via a qubit ''fusion'' operation, showing a strong violation of a three-particle Mermin inequality of |<A>|=3.10{+-}0.03. In addition, the entanglement properties of the cluster states are examined under {sigma}{sub z} and {sigma}{sub x} measurements on a qubit. This scheme could be extended to any desired number of qubits and represents an essential step for the optical one-way quantum computation.
