To address the challenge of effcient quantum control of a Bose-Einstein condensate (BEC) in a one-dimensional symmetric double-well potential, we propose a novel shortcuts-to-adiabaticity (STA) dynamical protocol built upon the scaling invariance of the time-dependent Gross-Pitaevskii (GP) equation and the generalized Ermakov equation, with inverse engineering adopted to design the control trajectory. This approach enables high-fidelity quantum state manipulation on significantly shorter timescales, effectively overcoming control diffculties caused by the double-well structure’s geometric complexity and inter-well coupling. We constructed two coeffcient-dependent STA protocols: one based on the harmonic trap frequency, where fidelity increases with lower and narrower Gaussian barriers and an optimal parameter set maximizes fidelity at fixed control effciency; the other driven by interaction strength, where fidelity improves with longer evolution times but shows pronounced oscillations and sharp drops in short durations, with higher and narrower central barriers reducing fidelity and the single-well configuration yielding the highest fidelity. This work establishes a theoretical framework for STA-based effcient quantum control of BECs in symmetric double-well systems, which achieves high-fidelity manipulation with drastically reduced evolution times compared to conventional adiabatic methods. The framework lays a theoretical foundation for precise BEC control and is extendable to multi-dimensional and complex trapping potentials, providing practical guidance for parameter optimization in broader quantum engineering applications.
