Abstract: Recently Yeo showed that the thermal states of one-dimensional Heisenberg XX model could be used for three-party quantum teleportation with W protocol. On the other hand Jin et al. showed that the best condition for three-party quantum teleportation would depend on the protocols. So in this article, for three-party quantum teleportation using thermal state of one-dimensional Heisenberg XX model, we will not only consider known three protocols but also suggest two protocols of new type. And we will obtain the best fidelity conditions to each protocol. We can see that type I W protocol and two protocols of new type provide best fidelity 79.
