外文摘要：Counterdiabatic driving(CD)offers a fast and robust route to manipulate quantum systems,which has widespread applications in quantum technologies.However,for higher-dimensional complex systems,the exact CD term involving the spectral properties of the system is difficult to calculate and generally takes a complicated form,impeding its experimental realization.Recently,many approximate methods have been proposed for designing CD passages in many-body systems.In this topical review,we focus on the CD formalism and briefly introduce several experimental constructions and applications of approximate CD driving in spin-chain models with nuclear magnetic resonance(NMR)systems.
