    "abstract": "We study a quantum state transfer between two qubits interacting with the\nends of a quantum wire consisting of linearly arranged spins coupled by an\nexcitation conserving, time-independent Hamiltonian. We show that if we control\nthe coupling between the source and the destination qubits and the ends of the\nwire, the evolution of the system can lead to an almost perfect transfer even\nin the case in which all nearest-neighbour couplings between the internal spins\nof the wire are equal.",
