Unifying adiabatic state-transfer protocols with $(α, β)$-hypergeometries

Adiabatic optimal control schemes are essential for advancing the practical implementation of quantum technologies. However, the vast array of possible adiabatic protocols, combined with their dependence on the particular quantum system and function-specific parameter ranges, complicates the task of discerning their respective strengths and limitations in arbitrary operations. In this work, we provide a unifying framework, called $(α,β)$-hypergeometries, that allows for flexible, noise-resistant, and easy-to-use implementation of enforced adiabatic dynamics for any multi-level quantum system. Moreover, this framework provides a comprehensive mapping of all adiabatic protocols through a universal cost function and offers an exact analytical characterization of the adiabatic dynamics. In particular, we derive precise expressions for infidelity resonances and establish performance guarantees in the adiabatic limit for any choice of $(α,β)$. We also discuss in detail the experimental feasibility of the resulting pulse shapes through analytical and numerical methods. Finally, we test our method for the optimal control of coherent information transfer through spin shuttling in silicon quantum dots with small valley splittings.
