    "abstract": "In this Letter we discuss the entanglement near a quantum phase transition by\nanalyzing the properties of the concurrence for a class of exactly solvable\nmodels in one dimension. We find that entanglement can be classified in the\nframework of scaling theory. Further, we reveal a profound difference between\nclassical correlations and the non-local quantum correlation, entanglement: the\ncorrelation length diverges at the phase transition, whereas entanglement in\ngeneral remains short ranged.",
