    "abstract": "An inseparability criterion based on the total variance of a pair of\nEinstein-Podolsky-Rosen type operators is proposed for continuous variable\nsystems. The criterion provides a sufficient condition for entanglement of any\ntwo-party continuous variable states. Furthermore, for all the Gaussian states,\nthis criterion turns out to be a necessary and sufficient condition for\ninseparability.",
