Globally controlled quantum wires for perfect qubit transport, mirroring, and computing

We describe a new design for a q wire with perfect transmission using a uniformly coupled Ising spin chain subject to global pulses. In addition to allowing for the perfect transport of single qubits, the design also yields the perfect mirroring of multiply encoded qubits within the wire. We further utilize this global-pulse generated perfect mirror operation as a clock cycle to perform universal quantum computation on these multiply encoded qubits where the interior of the q wire serves as the quantum memory while the q-wire ends perform one- and two-qubit gates.
