二分量子态的不可分准则

Inseparability criteria for bipartite quantum states

E. Shchukin, W. Vogel

摘要:

我们给出了二分谐波量子态部分转置非负的充要条件。的条件制定为一个无限系列的不等式的时刻的状态下研究。这个级数的任何不等式的违反是纠缠的充分条件。先前已知的纠缠条件被证明是我们的方法的特殊情况。

英文摘要:

We provide necessary and sufficient conditions for the partial transposition of bipartite harmonic quantum states to be nonnegative. The conditions are formulated as an infinite series of inequalities for the moments of the state under study. The violation of any inequality of this series is a sufficient condition for entanglement. Previously known entanglement conditions are shown to be special cases of our approach.
