  This article proposes a new method to increase the efficiency of stimulated
Raman adiabatic passage (STIRAP) in superconducting circuits using a shortcut
to the adiabaticity (STA) method. The STA speeds up the adiabatic process
before decoherence has a significant effect, thus leading to increased
efficiency. This method achieves fast, high-fidelity coherent population
transfer, known as super-adiabatic STIRAP (saSTIRAP), in a dressed
state-engineered $\Lambda$ system with polariton states in circuit QED.
