Long-range quantum entanglement measured at last
Physics World
JANUARY 22, 2022
Physicists have measured long-range quantum entanglement in special, topologically ordered phases of matter for the first time. This feat, which was achieved independently by two research groups using coupled superconducting circuits and arrays of atoms, could aid the development of robust memories for quantum computers. When certain materials are cooled to extremely low temperatures, exotic phases of matter appear.
