Optimal shortcut-to-adiabaticity quantum control

Published 26 Mar 2025 in quant-ph | (2503.20130v1)

Abstract: We introduce a new class of Shortcut-To-Adiabaticity (STA) protocols with minimal energy expenditure. The control process produces the same transformation as a counterdiabatic drive, but at the lowest possible energy cost. We apply optimal control theory to analytically design the latter for a qubit. We discuss the robustness of this control scheme with respect to a standard STA approach.
