    "abstract": "We consider pure quantum states of $N\\gg 1$ spins or qubits and study the\naverage entanglement that can be \\emph{localized} between two separated spins\nby performing local measurements on the other individual spins. We show that\nall classical correlation functions provide lower bounds to this\n\\emph{localizable entanglement}, which follows from the observation that\nclassical correlations can always be increased by doing appropriate local\nmeasurements on the other qubits. We analyze the localizable entanglement in\nfamiliar spin systems and illustrate the results on the hand of the Ising spin\nmodel, in which we observe characteristic features for a quantum phase\ntransition such as a diverging entanglement length.",
