    "abstract": "We consider teleportation of an arbitrary spin-1/2 target quantum state along\nthe ground state of a quantum spin chain. We present a decomposition of the\nHilbert space of the many body quantum state into 4 vector spaces. Within each\nof these subspaces, it is possible to take any superposition of states, and use\nprojective measurements to perform unit fidelity teleportation. Any such\nsuperposition is necessarily a spin liquid state. We also show that all total\nspin-0 quantum states belong in the same space, so that it is possible to\nperform unit fidelity teleportation over any one-dimensional spin-0 many body\nquantum state. We generalise to $n$-Bell states, and present some general\nbounds on fidelity of teleportation given a general state of a quantum spin\nchain.",
