Multilevel spectral navigation with geometric diabatic-adiabatic control

Year: 2026

Type: article

Abstract: We introduce a geometric framework for efficient few-parameter pulse optimization in multilevel quantum systems, enabling high-fidelity state transfer beyond the adiabatic limit. Our method interpolates smoothly between adiabatic and diabatic dynamics to minimize unwanted excitations and maximize desired transitions even within a multilevel structure. Crucially, for single-parameter pulse control, the optimization reduces to solving a first-order ordinary differential equation. We showcase the flexibility of our diabatic-adiabatic protocols through two examples in spin-based quantum information processing: state initialization and qubit state transfer.
