摘要
提出一个对未知三粒子W纠缠态的量子隐形传态方案.该方案用一个非最大GHZ纠缠态和一个非最大EPR纠缠态作为量子信道实现对未知经典W纠缠态的概率量子隐形传态和对未知一般W纠缠态受控的概率量子隐形传态.
In this paper, a protocol which can realize probabilistic quantum teleportation of an unknown classical tripartite W entangled state is proposed. Controlled probabilistie quantum teleportation of an unknown generic tripartite W entangled state with a non-maximal tripartite GHZ entangled state and a pair of non-maximal EPR entangled particles as the quantum channels can be realized too. The teleportation associates with the generalized Bell-basis measurement and the C-Not operate, respectively. After the base vector transformation, an auxiliary qubit which the initial state is in the zero state and the corresponding unitary transformation are included in this protocol.
