Quantum highway: Observation of minimal and maximal speed limits for few and many-body states
Zitian Zhu, Lei Gao, Zehang Bao +30
Tracking the time evolution of a quantum state allows one to verify the thermalization rate or the propagation speed of correlations in generic quantum systems. Inspired by the ene…
