论文摘要
不同网络结构中有不同的准备量子状态。整个节点总体上有两种情况：一个是平面中的四个节点，另一个是空间中的四个节点。在本文中，我们获得了可以在四节点网络结构中制备的量子状态的一些属性。其中包括熵的特性，纠缠度量，等级和多部分纠缠状态。这些属性还意味着网络结构对可以在四节点量子网络中制备的状态施加了一些约束。为了获得这些属性，我们还定义了满足对称要求的量子系统的$ n $ - 分分互面信息。
There are different preparable quantum states in different network structures. The four nodes as a whole has two situations: one is the four nodes in a plane, the other is the four nodes in the space. In this paper, we obtain some properties of the quantum states that can be prepared in four-node network structures. These include the properties of entropy, entanglement measure, rank and multipartite entangled states. These properties also mean that the network structures impose some constraints on the states that can be prepared in a four-node quantum network. In order to obtain these properties we also define $n$-partite mutual information of the quantum system, which satisfies symmetry requirement.
