Shortcuts to adiabaticity: Concepts, methods, and applications

D Guéry-Odelin, A Ruschhaupt, A Kiely… - Reviews of Modern …, 2019 - APS
Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

Quantum speed limits: from Heisenberg's uncertainty principle to optimal quantum control

Trade-off between speed and cost in shortcuts to adiabaticity

S Campbell, S Deffner - Physical review letters, 2017 - APS
Achieving effectively adiabatic dynamics is a ubiquitous goal in almost all areas of quantum

Classical and quantum shortcuts to adiabaticity for scale-invariant driving

S Deffner, C Jarzynski, A del Campo - Physical Review X, 2014 - APS
A shortcut to adiabaticity is a driving protocol that reproduces in a short time the same final
state that would result from an adiabatic, infinitely slow process. A powerful technique to …
