Abstract
As a crucial component of superconducting quantum computing, the three‐energy‐level quantum system, known as qutrit, along with qutrit gates, has garnered significant attention over the past decades, which highlights the significance of accomplishing state transfers between levels in multiqutrit systems as a critical task. Herein, the coupling is constructed via the all‐microwave approach. Both the coupling strength and Alternating Current stark shift are calibrated, based on which a fast (70 ns) state transfer from to is investigated and achieved through the stimulated Raman shortcut‐to‐adiabatic passage.
