摘要
为了在实际中更好的利用隐形传态方案去传送信息,给出了以混合纠缠态为资源来传送未知混合态的概率隐形传态方案,分析了以混合纠缠态为资源的隐形传送-未知量子态成功概率的上界.研究发现,作为信道资源的混合纠缠态的最小特征值决定了隐形传态的成功概率上界,此结果可视作纯态的隐形转移方案到混合态情形的推广.
In order to teleport the quantum state in realistic situation,a scheme of probabilistic teleportation an unknown mixed state with an entangled mixed state based on Bell measurement is presented. After analyzing the successful probability of teleportation, it is predicated that the process optimizes the probability of teleportation with the entangled mixed state, and then find that the probability of teleportation depends on it＇s the minimal eigenvalue. This scheme can be regarded as a generalization of the process presented by Bennett et al.
