5) Abstract
    -  Domain walls (DWs) on magnetic racetracks are at the core of the field of spintronics, providing a basic element for classical information processing [1]. Here, we show that mobile DWs also provide a blueprint for large-scale quantum computers [2]. Remarkably, these DW qubits showcase exceptional versatility, serving not only as stationary qubits, but also performing the role of solid-state flying qubits. We estimate that our DW qubits are long-lived because they can be operated at sweet spots to reduce potential noise sources. Single-qubit gates are deftly implemented by moving the DW, and two-qubit entangling gates exploit naturally emerging interactions between different DWs. These gates, sufficient for universal quantum computing, are fully compatible with current state-of-the-art experiments on racetrack memories. Further, we discuss possible strategies for qubit readout and initialization, paving the way toward future quantum computers based on mobile topological textures on magnetic racetracks.
