Brain-inspired chip runs near absolute zero and could transform quantum computing Date: June 12, 2026 Source: The University of Hong Kong Summary: Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable. By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “spikes” similar to those in the human brain.
