Japan-US team builds world’s first silicon spintronic chip for smart computers

Researchers from Tohoku University and NIST built the first spintronic p-bit on a silicon chip.

The device was fabricated with standard semiconductor processes and its probabilistic p-bit behavior was experimentally confirmed.

The result points to a manufacturing-compatible path to probabilistic computing hardware.

Such chips could help advance AI, machine learning, and optimization beyond conventional binary computing.
