Nonadiabatic unitary evolution with tailored time-dependent Hamiltonians can prepare many-body quantum states with various desired properties. We explore novel application of optimal control to problems ranging from cooling cold atoms beyond the current state of the art to beating the barrier of adiabaticity in the braiding of non-Abelian anyons. We show that highly nonadiabatic “bang-bang” protocols provide powerful shortcuts to the adiabatic evolution.
