    "abstract": "Cluster states serve as the central physical resource for the\nmeasurement-based quantum computation. We here present a simple experimental\ndemonstration of the scalable cluster-state-construction scheme proposed by\nBrowne and Rudolph. In our experiment, three-photon cluster states are created\nfrom two Bell states using linear optical devices. By observing a violation of\nthree-particle Mermin inequality of $|\u003c \\textit{A}\u003e| = 3.10\\pm0.03 $, we also\nfor the first time report a genuine three-photon entanglement. In addition, the\nentanglement properties of the cluster states are examined under $\\sigma_z$ and\n$\\sigma_x$ measurements on a qubit.",
