简介：我们为斜Bellstates的任意的混合的远距传物建议一个协议，隧道能与混合的纯最大地纠缠的statesor绑了的任何一个被构造，这被显示出纠缠的状态。我们也介绍协议认识到经由多粒子的斜贝尔状态的控制teleportationof混合混合了状态。我们的结果证明boundentangled状态也是在量通讯任务的重要、有用的资源。

简介：为在用部分纠缠的州的资源的一个量通讯系统的信息转移的传统的方法是量蒸馏或直接远距传物。以便减少在hop-by-hop传播花费并且在每个节点独立地执行的等待的时间，我们建议从来源节点与部分纠缠的状态衔接方法到teleport量状态到目的地节点的量。我们也证明衔接电路的设计的特定的量为越过多重中间的节点的部分纠缠的状态远距传物是可行的。比作二个传统的方法，我们的部分，纠纷量衔接方法使用更简单的逻辑门，更好的安全，和罐头处于更少的量资源状况被使用了。
