What's Happening?
A research team from Japan has discovered 'heavy fermions,' electrons with significantly increased mass, exhibiting quantum entanglement governed by Planckian time, the fundamental unit of time in quantum mechanics. This discovery, made in the material Cerium-Rhodium-Tin (CeRhSn), opens up possibilities for developing new types of quantum computers. Heavy fermions arise from strong interactions between conduction electrons and localized magnetic electrons, leading to unconventional superconductivity. The study revealed non-Fermi liquid behavior in CeRhSn at high temperatures, with heavy electron lifetimes approaching the Planckian limit, indicating quantum entanglement. Dr. Shin-ichi Kimura from The University of Osaka, who led the research, emphasized the significance of controlling entanglement in solid-state materials for quantum computing.
