摘要：
We propose a scheme to generate cluster-type entangled squeezed vacuum states via truss Kerr nonlinearity. Our scheme involves a single-photon source, balanced beam-splitters, mirrors, the Kerr medium and single-photon detectors. It is found that the generation of cluster-type entangled squeezed vacuum states is easier than the generation of cluster-type entangled coherent states. We also discuss the effect of an imprecise nonlinear phase shift between two modes on the fidelity and the experimental Feasibility of the proposed scheme. (C) 2014 Elsevier B.V. All rights reserved.
