W态的完美隐形传态与超密编码

Perfect Teleportation and Superdense Coding With W-States

Pankaj Agrawal, Arun Pati

摘要:

三个量子比特系统状态的真正三方纠缠可以根据随机局域操作和经典通信(SLOCC)进行分类。这种状态可以分为两类:GHZ状态和W状态。众所周知,GHZ态可以用于隐形传态和超密度编码,但原型W态不能。然而,我们发现,有一类W-状态,可以用于完美的隐形传态和超密集编码。

英文摘要:

True tripartite entanglement of the state of a system of three qubits can be classified on the basis of stochastic local operations and classical communications (SLOCC). Such states can be classified in two categories: GHZ states and W-states. It is known that GHZ states can be used for teleportation and superdense coding, but the prototype W-state cannot be. However, we show that there is a class of W-states that can be used for perfect teleportation and superdense coding.
