Two groups of researchers have independently devised a new recipe for quickly driving a generic quantum system into a desired ground state. Compared with previous recipes, it doesn't require as much detailed knowledge of the system.
A Shortcut to a Ground State
Theorists have proposed a universal recipe for trying to quickly prepare a system in a desired ground state without exciting it.

Universal Counterdiabatic Driving
Local counterdiabatic (CD) driving provides a systematic way of constructing a control protocol to approximately suppress the excitations resulting from changing some parameter(s) of a quantum system ...
