Superradiant phase transition seen for first time, breaks 50-year quantum barrier

Researchers at Rice University observed a superradiant phase transition (SRPT) for the first time, breaking a 50-year quantum barrier. The discovery occurred in an erbium-iron-oxygen crystal cooled to -457°F under a strong magnetic field. This phenomenon involves quantum particles fluctuating in sync, creating a new state of matter. The breakthrough could advance quantum computing, communication, and sensing technologies. The SRPT's properties, including quantum-squeezed states with reduced noise, may enhance measurement precision and improve quantum sensor performance.
