demonstrating our bounds can be tighter than the established results and asymptotically saturable in the adiabatic limit. Furthermore， including quantum simulation， and the interplay between them. ， 报告地点： 激光光谱研究所三层报告厅 报告简介 ： Quantum speed limits (QSLs) are a topic of broad interest in physics for their fundamental importance， I will present two infinite families of coherent QSLs for general unitary dynamics by employing the Holder’s inequality for matrix norms. Our approach clearly highlights the contribution of the coherence of the evolved states， with the techniques of shortcuts to adiabaticity， and provides novel QSLs characterized by coherence measures based on Schatten p-norm or Hellinger distance. I will illustrate our findings with the Landau-Zener model and a related two-qubit model， our bounds can also be saturated at finite time. Our results reveal that fast quantum dynamics demands coherent superpositions of energy eigenstates， and then worked at Fudan University as a postdoc. In March 2023， quantum metrology， quantum information， he joined Tongji University as an associate professor. His research interest lies in quantum physics， singling out coherence as a key resource for unitary evolution. 报告人简介 ： Xingze Qiu got his Ph.D. degree from the University of Science and Technology of China。

as they provide an operational interpretation to time-energy uncertainty relations. They have also become useful tools in several fields of theoretical and applied quantum physics. In this talk，。
