    "abstract": "Recently, Yeo and Chua [Phys. have given an explicit protocol for faithfully\nteleporting an arbitrary two-qubit state via a genuine four-qubit entangled\nstate, which is not reducible to a pair of Bell states. Here, we present a\ntransformation operator to give the criterion of for faithfully teleporting\narbitrary two-qubit states. The theoretical explanations of some quantum\nchannels are given by transformation operators. Furthermore, a new four-qubit\nentangled state quantum channel is presented.",
