    "abstract": "We propose a method to improve quantum state transfer in transmission lines.\nThe idea is to localize the information on the last qubit of a transmission\nline, by dynamically varying the coupling constants between the first and the\nlast pair of qubits. The fidelity of state transfer is higher then in a chain\nwith fixed coupling constants. The effect is stable against small fluctuations\nin the system parameters.",
