Flowchart and schematic of a probabilistic (p-bit) stochastic nanomagnet network for scalable, energy-efficient computing of combinatorial optimization problems: a giant spin Hall effect (GSHE) layer converts input voltage into a spin current (top left); a free circular nanomagnet with low thermal barrier serves as the free layer (top right).
