Group 1 - The core research led by North Carolina State University focuses on achieving superluminescence at room temperature, which is crucial for the development of quantum computing without the need for extremely low temperatures [1][2] - The study provides both experimental and theoretical foundations for generating macroscopic quantum coherence at room temperature, explaining why certain materials perform better in achieving exotic quantum states under environmental conditions [1][2] - The research highlights the phenomenon of "macroscopic quantum phase transition," where a large number of quantum particles synchronize to form a collective quantum state, akin to schools of fish swimming together or fireflies flashing in unison [1] Group 2 - The study reveals the specific mechanism behind the "thermal insulation" effect in hybrid perovskite materials, where excitons aggregate to form "soliton" structures when stimulated by laser [2] - The transition of polaritons from a disordered state to an ordered structure is directly observed, marking a significant advancement in understanding the formation of macroscopic quantum states [2] - This understanding allows for the design of high-temperature quantum materials, overcoming the limitations imposed by the need for low-temperature environments in current quantum technologies [2]
