我们求婚真( k , m )为经由多粒子的控制远距传物的阀值控制计划纠缠了状态,在到接收装置(鲍勃)的从一个发送者(艾莉斯)的一个量状态的远距传物在 m 监督人的控制下面以便这些监督人的 k ( k m )或更多能帮助跳的地方,恢复转移状态。由建设,我们的量隧道的任何人是任何二部分是无法分开的一个真多国参加的纠缠的状态。他们的性质著名 GHZ, W,和线性簇状态与那些被作比较并且形成对照,并且也,几个另外的真多国参加的纠缠的状态最近在文学介绍了。
We propose genuine (k, m)-threshold controlling schemes for controlled teleportation via multi-particle entangled states, where the teleportation of a quantum state from a sender (Alice) to a receiver (Bob) is under the control of m supervisors such that k (k≤ m) or more of these supervisors can help Bob recover the transferred state. By construction, anyone of our quantum channels is a genuine multipartite entangled state of which any two parts are inseparable. Their properties are compared and contrasted with those of the well-known GHZ, W, and linear cluster states, and also several other genuine multipartite entangled states recently introduced in the literature.
