多体连续变量纠缠

Multipartite continuous-variable entanglement

E. Shchukin, W. Vogel

摘要:

导出了多模量子态的所有部分转置非负的充要可观测条件。其结果是未成年人在给定状态的时刻的不平等的层次结构。违反任何不等式都是纠缠的充分条件。对于多模量子态的流形,可以证明完全纠缠。一个\textit{Mathematica}包给出了一个系统的测试层次的条件。

英文摘要:

Necessary and sufficient observable conditions for the nonnegativity of all partial transpositions of multi-mode quantum states are derived. The result is a hierarchy of inequalities for minors in terms of moments of the given state. Violations of any inequality is a sufficient condition for entanglement. Full entanglement can be certified for a manifold of multi-mode quantum states. A \textit{Mathematica} package is given for a systematic test of the hierarchy of conditions.
