Entanglement dynamics and decoherence of three-qubit system in a fermionic environment
XIAO SAN MA, An Min Wang, Xiao Dong Yang, Hao You · Journal of Physics A Mathematical and General · 2005
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.
