摘      要：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 *** check numerically the influences of the parameter fluctuations and dissipation on the scheme and show it to be *** scheme can also be generalized to other physical systems such as the ion trap.
