Researchers at the University of Hong Kong (HKU) have unveiled a significant advance in cryogenic electronics that could help overcome key challenges in quantum computing and support future deep space missions. The team, from HKU's Department of Electrical and Computer Engineering and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC), developed a programmable neuromorphic hardware platform capable of operating at temperatures near absolute zero.
The research was led by Professor Yuhao Zhang and PhD student Xin Yang. Their work introduces a new method for generating and controlling negative differential resistance (NDR) in industry standard Silicon Carbide (SiC) MOSFETs. Using this approach, the researchers demonstrated for the first time that a single transistor can reproduce the energy efficient "spiking" activity of biological neurons at temperatures as low as 10mK.
