| 摘 要： | 我们提出了一个制备五离子最大纠缠态的方案,并利用该纠缠态实现任意两量子比特的隐形传送和超密集编码。超密集编码的信息容量满足Holevo bound,这意味着通过发送三个量子比特可以传送五个经典比特的信息。

| Abstract: | We propose a scheme to generate a genuine five-qubit entangled state,and use this state for perfect teleportation of an arbitrary two-qubit state and superdense coding.The capacity of superdense coding of the state reaches the Holevo bound,which means that five classical bits can be transmitted by sending three qubits. |
