An algebraic approach to the study of multipartite entanglement

S. Di Martino, B. Militello, A. Messina

摘要:

介绍了一种研究纯态多体纠缠的简单代数方法,并给出了一类能检测纠缠的泛函。在此基础上,再现了一些已知的结果.事实上,通过研究引入的泛函的性质,它表明,这样的类的子集是严格连接到纯度。此外,提供了一个直接的和基本的解决方案的问题的同时最大化的三个适当的泛函的三个量子比特的状态,确认同时最大化的纠缠的所有可能的双分区只兼容的结构的GHZ态。

英文摘要:

A simple algebraic approach to the study of multipartite entanglement for pure states is introduced together with a class of suitable functionals able to detect entanglement. On this basis, some known results are reproduced. Indeed, by investigating the properties of the introduced functionals, it is shown that a subset of such class is strictly connected to the purity. Moreover, a direct and basic solution to the problem of the simultaneous maximization of three appropriate functionals for three-qubit states is provided, confirming that the simultaneous maximization of the entanglement for all possible bipartitions is compatible only with the structure of GHZ-states.
