Abstract
We propose a scheme to generate cluster-type entangled squeezed vacuum states via cross-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.
