摘要：
Quantum teleportation is investigated by using the entangled states of two-qubit Heisenberg XYZ chain in an external uniform magnetic field as resources with intrinsic decoherence taken into account. The influence of intrinsic decoherence on quantum teleportation varies in different initial systems. (c) 2006 Elsevier B.V. All rights reserved.
