Stimulated Raman adiabatic passage (STIRAP) is a standard technique in realizing robust quantum state control for many applications in physics, chemistry, and beyond, against experimental imperfections. However, STIRAP is susceptible to decoherence due to long evolution time. Here, we develop an alternative approach, termed stimulated Raman user-defined passage, called STIRUP, which allows users to design different fast and robust passages against both decoherence and imperfection. Comparing with shortcut to adiabaticity and its' variants, this approach is simpler and more efficient to extend many-level and many-qubit system. Furthermore, STIRUP has many important physical applications such as geometric phase measurement, coherent population transfer, and quantum state preparation. Specifically, we can realize high-fidelity and robust state transfer and entangled state generation via STIRUP with state-of-the-art experimental implementations of superconducting circuits.
