    "abstract": "An open ended spin chain can serves as a quantum data bus for the coherent\ntransfer of quantum state information. In this paper, we investigate the\nefficiency of such quantum spin channels which work in a decoherence\nenvironment. Our results show that, the decoherence will significantly reduce\nthe fidelity of quantum communication through the spin channels. Generally\nspeaking, as the distance increases, the decoherence effects become more\nserious, which will put some constraints on the spin chains for long distance\nquantum state transfer.",
