| Abstract: | The separatability of states in infinite dimensional quantum systems is discussed,some necessary conditions for separable states are presented in infinite dimensional quantum systems,some inequalities are obtained for separable states.These results extend the results of Otfried Guhne(Phys Rev Lett,2004)and Zhang ChengJie(Phys Rev A,2010),which reinforces the exploration of entanglement for states in infinite dimensional quantum systems. |
