摘要：

A criterion for he tquantum teleportation of an arbitrary N-particle state via a 2 N-particle quantum channel is presented by introducing a term of the "judgment operator". Using the criterion, not only the qualitative judgment of the possibility of successful teleportation can be made but also the quantitative calculation of the probability of successful teleportation can be explicitly given. In addition, a new genuine four-qubit entangled state is proposed, which could not belong to the category of previously known states under stochastic local operations and classical communication.
