Builder The claim is about what the hardware does, and the philosophy is left open
Hyunsoo Yang is Professor in the Department of Electrical and Computer Engineering at the National University of Singapore, where his laboratory fabricates and characterizes spin-transfer torque and spin-orbit torque magnetic tunnel junctions (MTJs), topological spintronic materials, and in-memory computing arrays.
As senior co-author of 250 Magnetic Tunnel Junctions-Based Probabilistic Ising Machine (Nature Communications, 2026, doi:10.1038/s41467-026-72020-8, arXiv:2506.14590) alongside Giovanni Finocchio, Shuhan Yang, and Andrea Grimaldi, Yang led the experimental integration of 250 nanoscale STT-MTJ devices with an FPGA control plane to form a programmable probabilistic Ising machine. Short-pulse switching characterizations on the STT-MTJ array indicate that nanosecond-regime spintronic p-bit engines can reach orders-of-magnitude gains in energy efficiency and sampling throughput compared to graphics processing units.
Yang is classified as a Builder on this site, contributing device fabrication and high-speed switching data to the physical substrate layer of thermodynamic and probabilistic computing.
