Multi-level spectral navigation with geometric diabatic-adiabatic control

Year: 2026

Type: article

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