    "abstract": "We propose a method for quantum state transfer in spin chains using an\nadiabatic passage technique. Modifying even and odd nearest-neighbour couplings\nin time allows to achieve transfer fidelities arbitrarily close to one, without\nthe need for a precise control of coupling strengths and timing. We study in\ndetail transfer by adiabatic passage in a spin-1 chain governed by a\ngeneralized Heisenberg Hamiltonian. We consider optimization of the transfer\nprocess applying optimal control techniques. We discuss a realistic\nexperimental implementation using cold atomic gases confined in deep optical\nlattices.",
