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