    "abstract": "We describe a generalization of the cluster-state model of quantum\ncomputation to continuous-variable systems, along with a proposal for an\noptical implementation using squeezed-light sources, linear optics, and\nhomodyne detection. For universal quantum computation, a nonlinear element is\nrequired. This can be satisfied by adding to the toolbox any single-mode\nnon-Gaussian measurement, while the initial cluster state itself remains\nGaussian. Homodyne detection alone suffices to perform an arbitrary multi-mode\nGaussian transformation via the cluster state. We also propose an experiment to\ndemonstrate cluster-based error reduction when implementing Gaussian\noperations.",
