    "abstract": "We analyse quantum teleportation (QT) and entanglement swapping (ES) for spin\nsystems. If the permitted operations are restricted to the Ising interaction,\nplus local rotations and spin measurements, high-fidelity teleportation is\nachievable for quantum states that are close to the maximally weighted spin\nstate. ES is achieved, and is maximized for a combination of entangled states\nand Bell measurements that is different from the QT case. If more general local\nunitary transformations are considered, then it is possible to achieve perfect\nteleportation and ES.",
