Probabilistic Ising machines (PIMs) are advanced and specialized computing systems that could tackle computationally hard problems, such as optimization or integer factorization tasks, more efficiently than classical systems. A class of PIMs that are intensively investigated use magnetic devices to inject randomness into a digital transistor-based circuit. "Our probabilistic computer consists of an array of bistable probabilistic elements (called probabilistic bits or p-bits)," explained Amiri. Notably, although it relies on VMTJs, the new approach is also compatible with established CMOS manufacturing processes and digital design strategies. "Our next step will be to adapt this design to implement problems other than factorization," added Amiri.
