    "abstract": "Consider an infinite collection of qubits arranged in a line, such that every\npair of nearest neighbors is entangled: an \"entangled chain.\" In this paper we\nconsider entangled chains with translational invariance and ask how large one\ncan make the nearest neighbor entanglement. We find that it is possible to\nachieve an entanglement of formation equal to 0.285 ebits between each pair of\nnearest neighbors, and that this is the best one can do under certain\nassumptions about the state of the chain.",
