Optimally robust shortcuts to population inversion in two-level quantum systems

Abstract

We examine the stability versus different types of perturbations of recently proposed shortcuts to adiabaticity to speed up the population inversion of a two-level quantum system. We find the optimally robust processes by using invariant-based engineering of the Hamiltonian. Amplitude noise and systematic errors require different optimal protocols. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
