Entanglement conditions for multi-mode states
Zong-Guo Li, Shao-Ming Fei, Zhi-Xi Wang and Ke Wu
Abstract
We provide a class of inequalities for detecting entanglements in multi-mode systems. Necessary conditions for fully separable, bi-separable and sufficient conditions for fully entangled states are explicitly presented.
