常见的纠缠证人及其特征

Common entanglement witnesses and their characteristics

Nirman Ganguly, Satyabrata Adhikari, A. S. Majumdar

摘要:

我们研究了如何为某类状态找到共同的纠缠见证,并将研究扩展到施密特数见证的情况。我们还介绍了公共可分解和不可分解的见证算子的概念,这是特别有用的构造一个共同的见证之一的纠缠态是一个积极的部分转置。我们的方法是说明与适当的例子的帮助下quutrit系统。

英文摘要:

We investigate the issue of finding common entanglement witness for certain class of states and extend this study to the case of Schmidt number witnesses. We also introduce the notion of common decomposable and non-decomposable witness operators which is specially useful for constructing a common witness where one of the entangled states is with a positive partial transpose. Our approach is illustrated with the help of suitable examples of qutrit systems.
