Coherent ma gnonic excitations of low-loss magnetic materials can wire together these qubits for sensing\, memory\, and computing. Coherent magnonics may reduce the size of superconducting qubits (which otherwise struggle with the lar ge scale of microwave excitations) and may increase the size of spin-based qubit networks (which otherwise contend with the very short distances of dipolar or exchange interactions). Compared to photonic devices\, these ma gnonic devices require minimal energy and space. However\, efforts to expl oit coherent magnonic systems for quantum information science will require a new understanding of the linewidths of low-loss magnonic materials shap ed into novel structures and operating at dilution-refrigerator temperatur es. This lecture will introduce the fundamental requirements for practical ly linking quantum objects into large-scale coherent quantum systems as we ll as the advantages of coherent magnonics for next-generation quantum coh erent systems (i.e.\, spin-entangling quantum gates [1]). Other critical c hallenges for quantum information science then will motivate the developme nt of coherent magnonics for quantum transduction from “stationary” sp in systems to “flying” magnons and for quantum memory [2]–[4]. Final ly\, the advantages of all-magnon quantum information technologies that re ly on manipulating and encoding quantum information in superpositions of f ixed magnon number states will highlight the potential of new magnetic mat erials\, devices\, and systems.\nKey publications:\n[1] M.
