Roadmap on spin-wave computing concepts

Magnonics is the field of science investigating the physical properties of spin waves and utilizing them for data processing. Scalability down to the atomic dimensions, operations from the GHz to THz frequency range, utilization of the pronounced nonlinear and nonreciprocal phenomena, compatibility with CMOS are just a few of many advantages offered by magnons. Although magnonics is still primarily positioned in the academic domain, the scope of the scientific and technological challenges covered by the field are extensively investigated and many proof-of-concept prototypes have already been realized in the laboratory. This Roadmap is a product of the collective work of many Authors, covering versatile spin-wave computing approaches, their conceptual building blocks, and the underlying physical mechanisms. In particular, the Roadmap discusses the computation operations with Boolean digital data, unconventional approaches like neuromorphic computing, and the progress towards magnon-based quantum computing. The article is organized as a collection of subsections grouped into seven large thematic sections. Each subsection is prepared by one or a group of Authors and concludes with a brief description of the current challenges and the outlook of the further evolution of the research directions
