Heavy fermions entangled: Discovery of Planckian time limit opens doors to novel quantum technologies

SMRTR summary

Japanese researchers discovered that "heavy fermions"—electrons with enhanced mass—exhibit quantum entanglement governed by the fundamental Planckian time limit in cerium-rhodium-tin material. This breakthrough reveals entangled states persisting near room temperature, potentially enabling the development of novel solid-state quantum computers that harness this quantum phenomenon.
