SiC Transistors Mimic Brain Cells At 10mK For Quantum Control - Quantum Zeitgeist

Researchers at the University of Hong Kong have demonstrated the first 'brain-like' chip capable of mimicking biological neurons at an extremely low temperature of 10 millikelvin, marking a significan... Read original →

The University of Hong Kong, China’s demonstration of SiC MOSFETs exhibiting neuron-like behavior at 10mK leverages electron-donor impact ionization to achieve S-shaped NDR—bypassing cryogenic CMOS mobility collapse and enabling on-chip quantum control. This forces integration of EUV-based 3nm processes with wide-bandgap materials, repurposing existing 300mm power semiconductor fabs. While SiC devices currently evade U.S. export controls, their use in quantum systems may prompt BIS to reclassify them under 'advanced computing hardware,' complicating global R&D partnerships. Competitors like Infineon and Wolfspeed will fast-track neuromorphic SiC programs, while TSMC (Taiwan, China) could counter with its cryo-CMOS 3nm platform. Within 18 months, expect EDA toolchains for cryogenic ASICs to emerge, with space agencies adopting localized quantum controllers—ushering in a vertically integrated quantum hardware stack.
