Recently, a new method, which can significantly speed up adiabatic quantumstate transfer by using dressed states, was proposed by Baksic \emph{et~al.}[Phys. Rev. Lett. \textbf{116}, 230503 (2016)]. Assisted by quantum Zenodynamics, we develop this dressed-state method to achieve shortcuts to completeand fractional stimulated Raman adiabatic passage for speeding up adiabatictwo-atom quantum state transfer and maximum entanglement generation,respectively. By means of some numerical simulations, we determine theparameters used in the scheme which can guarantee the feasibility andefficiency both in theory and experiment. Besides, we give strict numericalsimulations to discuss the scheme's robustness, and the results show the schemeis robust against the variations in the parameters, atomic spontaneousemissions and the photon leakages from the cavity.
