    "abstract": "It is expected that quantum wires (q-wires), will be required to transport\nquantum information within many quantum computer implementations. Here we\ndescribe a new design for a q-wire with perfect transmission using a uniformly\ncoupled Ising spin chain subject to global (homogeneously-applied) pulses.\nBesides allowing for perfect transport of single qubits, the design also yields\nthe perfect ``mirroring\u0027\u0027 of multiply encoded qubits within the wire. We\nfurther utilise this global-pulse generated perfect mirror operation as a\n``clock cycle\u0027\u0027 to perform universal quantum computation on these multiply\nencoded qubits. We demonstrate the operation of single and two-qubit quantum\nlogic gates and show that only $N-1$ complete mirror cycles are required to\nexecute a quantum Fourier transform on $N$ qubits encoded within the q-wire.",
