论文摘要
我们研究纠缠见证人，并根据对称的信息完成测量（SIC-POVM）提出了纠缠见证人的构建。一些例子显示了我们证人的能力，并且可以发现该证人比SIC-POVM给出的以前的可分离性方法更纠缠。更重要的是，与SIC-POVM的维度依赖性相比，我们还可以始终从一般的对称信息完整的测量（GSIC-POVM）中构建纠缠证人。
We study entanglement witness and present a construction of entanglement witnesses in terms of the symmetric informationally complete measurements (SIC-POVM). The capability of our witness is shown by some examples and it can be found this witness detects more entanglement than previous separability method given also by SIC-POVM. What's more, comparing with the dimension dependence of SIC-POVM, we also give the entanglement witnesses can be always constructed from general symmetric informationally complete measurements (GSIC-POVM).
