Proves 1D thermal quantum states decompose into constant-depth circuit components, establishing universal bounds on thermal entanglement and enabling efficient state preparation with classical sampling.
Researchers rigorously proved quantum mechanics prevents systems from thermalizing faster than half the Planckian timescale, establishing a fundamental speed limit using quantum information theory and metrology.
Researchers clarify 'instant thermalization' in SYK models by analyzing three thermalization measures. Surprisingly, thermalization rates scale as Γ∼Tf·q⁻¹ rather than diverging, with the effect dependent on which correlations are measured.
