    "abstract": "The scalability of solid state quantum computation relies on the ability of\nconnecting the qubits to the macroscopic world. Quantum chains can be used as\nquantum wires to keep regions of external control at a distance. However even\nin the absence of external noise their transfer fidelity is too low to assure\nreliable connections. We propose a method of optimizing the fidelity by minimal\nusage of the available resources, consisting of applying a suitable sequence of\ntwo-qubit gates at the end of the chain. Our scheme allows also the preparation\nof states in the first excitation sector as well as cooling.",
