Inseparability criterion for continuous variable systems
Lu-Ming Duan, G. Giedke, J. I. Cirac, P. Zoller
Abstract
An inseparability criterion based on the total variance of a pair of Einstein-Podolsky-Rosen type operators is proposed for continuous variable systems. The criterion provides a sufficient condition for entanglement of any two-party continuous variable states. Furthermore, for all the Gaussian states, this criterion turns out to be a necessary and sufficient condition for inseparability.
