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 lAl =3.10±0.03. In addition, the entanglement properties of the cluster states are examined under σz and σx 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.
