| 摘 要： | Under the enlightenment of the scheme of Mancini and Bose Phys. Rev. A 70 （2004）022307], we discuss two-atom entanglement in a fibre-connected triple-distant-atom system. Under adiabatic approximation, we obtain an effective Hamiltonian in form of the triple-body Ising-model interaction, The existence of a third atom is found to damage the other two-atom entanglement, The nearest-neighbouring two atoms that share a larger Ising strength are more strongly entangled.
