Abstract: Cluster states are an important class of multiparticle entangled states with entanglement properties suited for quantum computation. The one-way model proposed by Raussendorf and Briegel processes information entirely through adaptive single-qubit measurements on such a state. In this talk, I will discuss experiments with cluster states encoded in the polarization state of four photons. Using these states, a universal set of one- and two-qubit operations were demonstrated. This cluster state was then used to implement Grover's search algorithm for two qubits. If time permits, I will also present a novel experimental test of quantum nonlocality exploiting the cluster's entanglement properties.
