    Abstract

    The fidelity of threephoton W state teleportation token bus network is calculated. The calculation indicates that, for a given analysis angle θ, the fidelity are related only with the coefficient |a|2s during the processes of quantum network communication. With the increase of analysis angles, the maximum fidelity of the corresponding coefficient |a|2s correspondingly reduced. When θ=π/4, π/2, 3π/4, the fidelity are up to the maximum 1, and the corresponding |a|2s are 0.724, 0.5, and 0.276, respectively. For a given coefficient |a|, the fidelity are related only with the analysis angles θ. If |a|=0, the fidelity is always 0 regardless of the value of θ. When |a|=|b|=0.7071 and θ=π/2, 3π/2, the fidelity are up to the maximum 1.
