Abstract

We propose an efficient scheme for generation of three-atom singlet state in a bimodal cavity based on quantum Zeno dynamics and the large detuning condition. The influence of decoherence induced by cavity decay and atomic spontaneous emission is also discussed by numerical calculation. The advantages of the scheme are that the initial input states of atoms are not entangled and the fidelity is insensitive to cavity decay and atomic spontaneous emission due to no exciting the cavity fields during the whole evolution and the large detuning condition.
