SWIM · A SpinWave Ising Machine

The SWIM project will tackle a critical challenge for the emerging field of Ising Machines (IMs): the development of miniaturized, low-power, and low-cost IMs with high computational power, commercial feasibility, and speed beyond classical Von-Neuman and CMOS-based solutions. SWIM will achieve this through exploiting exceptionally slow propagating spinwaves and using off-the-shelf power-efficient microwave electronic components and circuits in an entirely novel architecture of YIG-film-based Ising Machines (IM) with potential performance many orders of magnitude beyond the state-of-the-art. The project's objectives are to explore the possibilities of using spinwaves and microwave signals to construct multiphysical time-multiplexed IMs and study and determine the spinwave phenomena and electronic design techniques needed to improve targeted parameters: power consumption, Ising spin capacity, physical size, and speed performance. The objectives will be achieved through a multidisciplinary approach involving classical and modern methods. Theoretical magnetostatic description of propagating spinwaves, micromagnetic simulation methods, and electronic circuit design theory will be used for the SWIM design. Brillouin light scattering spectroscopy and microwave measurement techniques will be used for the analysis of the results and further improvement.
