| Abstract: | Two protocols for transmitting an unknown single-photon state and anunknown non-maximally entangled EPR state are presented by using thequantum channel of three-phonton GHZ (Greenberger-Horne-Zeilinger)state, which can be realized with unitary success probability whencollective noise is taken into account. The protocols can also begeneralized to transmit multi-photon state or to realize quantumcommunication in collective noise channel. |
