Topological spin textures in magnetic materials and arrangements of electric dipoles in ferroelectrics are promising candidates for next-generation information technology and unconventional computing. Exciting examples are magnetic skyrmions and ferroelectric domain walls. In their article an international team of researchers (Germany, Norway) discussed how the physical properties of these topological nanoscale systems can be leveraged for reservoir computing, that is, for translating non-linear problems into linearly solvable ones. Topological nanoscale systems fulfill the requirements for non-linearity, complexity, short-term memory and reproducibility, giving new opportunities for the downscaling of devices, enhanced complexity and versatile input and readout options. They also discussed the practical challenges and opportunities for exploiting the unique properties of these systems… read more. TECHNICAL ARTICLE
