摘要：

In this paper, we present a scheme for quantum teleportation of an arbitrary two-particle state via entangled W state or W-like state channels. We find that the success of teleportation is probabilistic and the corresponding probability only relates to the smaller coefficients of the quantum channels. We further show that the quantum teleportation could achieve higher probability using W-like state as a channel than the W state.
