Abstract
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.
