Abstract

By resorting to the tensor analysis, we derived an explicit CPM (channel parameter matrix) criterion based on the Bell state measurements. This criterion can be used to judge whether a four-qubit state can be employed as quantum channel or not for teleporting a general two-qubit state. According to this criterion, we presented a variety of quantum channels for faithful and deterministic teleportation of a general two-qubit state, which can provide more flexible choices for the experimenters.
