    "abstract": "A general framework is developed for separating classical and quantum\ncorrelations in a multipartite system. Entanglement is defined as the\ndifference in the correlation information encoded by the state of a system and\na suitably defined separable state with the same marginals. A generalization of\nthe Schmidt decomposition is developed to implement the separation of\ncorrelations for any pure, multipartite state. The measure based on this\ndecomposition is a generalization of the entanglement of formation to\nmultipartite systems, provides an upper bound for the relative entropy of\nentanglement, and is directly computable on pure states. The example of pure\nthree-qubit states is analyzed in detail, and a classification based on\nminimal, four-term decompositions is developed.",
