    "abstract": "We present a method for encoding and transporting qubits within a dimerized\nHeisenberg spin-1/2 chain. Logical qubits are localized at the domain walls\nthat separate the two possible dimerized states. The domain walls can be moved\nto produce \"flying spin qubits\". The topological nature of these states makes\nthem stable against a wide class of perturbations. Pairs of domain walls can be\nused to generate Einstein-Podolsky-Rosen pairs of entangled qubits. We discuss\nspeed limitations within an exactly solvable three-spin model and describe a\npossible physical realization using quantum dot arrays.",
