Overview

• A team led by North Carolina State University and including Duke, Boston University and Institut Polytechnique de Paris published a Nature paper on May 28 detailing the conditions and mechanism for exotic quantum states in hybrid perovskites at elevated temperatures.
• When polarons in the perovskite lattice exceed a threshold density, they align into solitons—coherent groupings that dampen thermal noise and preserve macroscopic quantum phase transitions.
• Laser excitation experiments directly observed polarons clustering into solitons within the hybrid perovskite, confirming their role in sustaining quantum coherence at higher temperatures.
• The study combines theoretical modeling, lattice simulations and temperature-resilience tests to establish quantitative design parameters for new high-temperature quantum materials.
• By enabling macroscopic quantum effects without ultra-low cooling, this work paves the way for more practical quantum computing, communication, sensing and cryptography applications.
