Scientists at Japan's Tohoku University, Italy's University of Messina, and the University of California, Santa Barbara have engineered a scaled-up probabilistic computer (p-computer) with stochastic spintronic devices.
The researchers demonstrated how stochastic magnetic tunnel junction (sMTJ)-based probabilistic bits (p-bits) can be integrated with field-programmable gate arrays (FPGAs) to implement larger p-bit networks in hardware.
They also executed a simulated quantum annealing algorithm in heterogeneous MTJ + FPGA p-computers with systematic assessments for hard combinatorial optimization problems.
The researchers benchmarked sMTJ-based p-computer performance against that of classical computing hardware, including graphics processing units and Tensor Processing Units, and found it yields superior throughput and power consumption compared to conventional technologies.
