摘　　要：本文通过一系列的双量子位逻辑门构造非对称多体量子纠缠态。以此态作为量子隐形传输通道,利用全局幺正操作和定域性测量,我们可以让未知态在任意一个接收端重现,从而实现量子信息一对多的网络式传输。同时,充分考虑实际量子系统的局域环境噪声对量子传输效率的影响。The asymmetric multipartite entangled states is realized with a series of two-qubit quantum gates in the superconducting quantum systems.The protocol of quantum network teleportation between one sender and many receivers is studied in the channel of the asymmetric entangled states.An arbitrary unknown state can be recovered at any one of the receivers by means of global unitary operations and local measurements.The effect of the noises from the local environment on the successful probability of transferring states is under consideration.
