Criteria of minimum squeezing for quantum cluster state generation

In this paper, we assess the possibilities of generating cluster states with different topologies possessed by the finite squeezing resource of the initial oscillators used to generate the cluster state. We obtained the condition on minimum squeezing required for generating a cluster with a given to...

Description
Summary:In this paper, we assess the possibilities of generating cluster states with different topologies possessed by the finite squeezing resource of the initial oscillators used to generate the cluster state. We obtained the condition on minimum squeezing required for generating a cluster with a given topology as a simple estimation in terms of the coefficients of the adjacency matrix.
