Abstract Stimulated Raman adiabatic passage (STIRAP) is a widely used protocol to realize high-fidelity and robust quantum control in various systems. However, further application of this superconducting qubits limited by population leakage caused the only weak anharmonicity. Here, we introduce an optimally controlled shortcut-to-adiabatic (STA) technique speed-up STIRAP qudit. By modifying shapes pulses, experimentally fast (32 ns) (0.996 ± 0.005) state transfer. In addition, demonstrate that our against parameter perturbations. Our stimulated transition provides efficient practical approach for information processing.
