    "abstract": "Control of the transfer of quantum information encoded in quantum wavepackets\nmoving along a spin chain is demonstrated. Specifically, based on a\nrelationship with control in a paradigm of quantum chaos, it is shown that\nwavepackets with slow dispersion can automatically emerge from a class of\ninitial superposition states involving only a few spins, and that arbitrary\nunspecified travelling wavepackets can be nondestructively stopped and later\nrelaunched with perfection. The results establish an interesting application of\nquantum chaos studies in quantum information science.",
