This study bridges the gap between slow, frozen spin glass states used in potential data storage and the ultrafast dynamics of the Sachdev-Ye-Kitaev model originally developed for black hole physics. By mathematically demonstrating how quantum fluctuations can trigger this transition even at low temperatures, researchers have identified a pathway to control information scrambling in future quantum technologies. The work provides critical theoretical tools for understanding fundamental limits in quantum memory and computing architectures.
Quantum magnets link slow data storage to black hole physics

University at Buffalo physicists discovered a mathematical solution connecting frustrated quantum magnets, like spin glasses, to the ultrafast behavior of the Sachdev-Ye-Kitaev model—used in black hole physics.
University at Buffalo physicists have discovered a mathematical solution revealing how a frustrated quantum magnet transitions from ultraslow behavior to dynamics resembling those near a black hole. The team connected spin glasses, states of matter where atomic magnets become effectively frozen, to the fast, entangled states described by the Sachdev-Ye-Kitaev (SYK) model. “We’ve essentially found the math that…
