HKU Engineering Develops World-First Cryogenic Neuromorphic Chip to Advance Quantum Scaling

Solid-state electronics researchers from the University of Hong Kong’s (HKU) Department of Electrical and Computer Engineering, working alongside the Centre for Advanced Semiconductors and Integrated Circuits (CASIC), have achieved a significant material physics breakthrough in cryogenic electronics. Led by Professor Yuhao Zhang and PhD student Xin Yang, the team has engineered a programmable, brain-like neuromorphic hardware platform that operates near absolute zero (10 mK). Published in Nature Communications, the study demonstrates how the intrinsic atomic properties of industry-standard Silicon Carbide (SiC) power transistors can be harnessed to construct energy-efficient, local data processing networks inside quantum dilution refrigerators. This milestone introduces a practical pathway to eliminate the severe wiring bottlenecks that currently limit the scalability of universal quantum computers.
