Abstract We propose to engineer qutrit-qutrit entanglement through resonant atom-cavity interaction assisted by moderate laser driving, study two parameter regimes, respectively, of asymmetric atom-laser coupling and of asymmetric atom-cavity coupling, and find that both the coupling regimes possess the advantage of short operation time, compared with the previous ones achieved by dispersive interaction, adiabatic passage, and even quantum Zeno dynamics. We check numerically the influences of the parameter fluctuations and dissipation on the scheme and show it to be robust. The scheme can also be generalized to other physical systems such as the ion trap.
