摘要: We investigate the teleportation of an entangled state via a couple of quantum channels, which are composed of a spin-1/2 Heisenberg dimer in two infinite Ising-Heisenberg chains. The heterotrimetallic coordination polymer CuMn(L1)] [Fe(bpb)(CN)2]·ClO4·H2O (abbreviated as Fe-Mn-Cu) can be regarded as an actual material for this chain. We apply the transfer-matrix approach to obtain the density operator for the Heisenberg dimer and use the standard teleportation protocol to derive the analytical expression of the density matrix of the output state and the average fidelity of the entanglement teleportation. We study the effects of the temperature T, anisotropy coupling parameter , Heisenberg coupling parameter J2 and external magnetic field h on the quantum channels. The results show that anisotropy coupling and Heisenberg coupling J2 can favor the generation of the output concurrence and expand the scope of the successful average fidelity.
