Abstract
The dynamics of coherence in a two-qubit Heisenberg XXX model with magnetic field in the presence of the intrinsic decoherence is investigated. We discuss the influence of dipole parameter D, spin distance r, magnetic field Bz and initial state parameter α on coherence of the long time limit situation. Then, we discuss how decoherence changes with time with the initial state parameter α and the decoherence parameter γ.
