摘要
We study the entanglement dynamics of the three-qubit system in a symmetry-broken environment consisting of a fermionic bath. Decoherence induced by the bath is analysed. We find that the entanglement of states will decrease or remain unchanged under the system-bath interaction. The class of decoherence-free states of the three-qubit system of our model has been found out.
