无极值性和生成性的最优不可分解证据集

Optimal indecomposable witnesses without extremality as well as spanning property

Kil-Chan Ha, Hoseog Yu

摘要:

关于最优不可分解纠缠证据的一个有趣问题是,是否存在既不具有生成性质又不与极值正线性映射相关联的最优不可分解证据。在这里,我们通过检验Qi和Hou [J. Phys. A { \bf 44},215305(2100)]构造的正线性映射的极值来否定地回答这个问题。

英文摘要:

One of the interesting problems on optimal indecomposable entanglement witnesses is whether there exists an optimal indecomposable witness which neither has the spanning property nor is associated with extremal positive linear map. Here, we answer this question negatively by examining the extremality of the positive linear maps constructed by Qi and Hou [J. Phys. A {\bf 44}, 215305 (2100)].
