摘要

本文研究了资源约束下集群状态配置的优化问题。考虑到振子压缩的有限程度，我们提出了一种分配簇态权系数的方法，以最大化簇中的成对纠缠。我们发现了对聚类权重系数以及压缩程度施加的约束。此外，我们提出了一种利用社会网络理论中的中心性度量来寻找聚类状态下权重系数的最优分布的方法。

Aspects of Configuring Weighted Cluster States Under Resource Constraints

This work studies optimization of cluster state configurations under resource constraints. Taking into account the finite degree of oscillator squeezing, we proposed a way of distributing the weight coefficients of a cluster state for maximizing pairwise entanglement in the cluster. We found constraints imposed on the cluster weight coefficients, as well as on the squeezing degree. In addition, we proposed a method that uses the centrality measure from social network theory for finding the optimal distribution of weight coefficients in a cluster state.
