In this talk we shall first review the techniques of shortcuts to adiabaticity by focusing on the experimental progress. Later, we explore how to design the shortcuts to adiabaticity for controlling BECs and soliton in trapping potentials based on Lagrangian variational method. Next, we focus on the effects of many-body coherence on the quantum speed limit and shortcuts to adiabaticity in ultracold atomic gases. To illustrate the effect of the coherence on the dynamics we consider squeezing the anharmonic potential which confines the spinless fermions and the bosonic Tonks-Girardeau gas, and find that the quantum speed limit exhibits subtle differences between the atomic species. Then, we exemplify that other applications of shortcuts to adiabaticity for the driven linear and nonlinear quantum systems with the applications in quantum information processing. Finally, the talk ends up with some perspectives on the digitized adiabatic quantum computing and machine learning with shortcuts to adiabaticity.
