Entropic Entanglement Criteria for Continuous Variables
arXiv:0909.0147 · doi:10.1103/PhysRevLett.103.160505
Abstract
We derive several entanglement criteria for bipartite continuous variable quantum systems based on the Shannon entropy. These criteria are more sensitive than those involving only second-order moments, and are equivalent to well-known variance product tests in the case of Gaussian states. Furthermore, they involve only a pair of quadrature measurements, and will thus should prove extremely useful the experimental identification of entanglement.
