| 摘 要： | 提出了一种利用4-qubit簇态(Cluster)实现两比特量子态分享的QED方案,因为只需要对粒子的直积测量,从而避免了对粒子的联合Bell测量并使测量过程变得直接、方便和易于探测,授权者可以通过简单的对粒子的局域操作得以恢复传输的量子态。

| Abstract: | We propose a protocol for realizing two-bit quantum-state sharing with 4-qubit cluster state through cavity QED,because we only need the direct product measurement to particles and avoid the joint Bell measurement of particles,so that the process of measurement become direct,convenience and easy to be detected.Authorizer can resume quantum states of transmission through a simple local operation on the particles. |
