\begin{document}$\sqrt {{{\left( {{{2\gamma } \mathord{\left/ {\vphantom {{2\gamma } a}} \right. } a}} \right)}^2} - 1} $\end{document} and \begin{document}$ \sqrt {2{\varGamma \mathord{\left/ {\vphantom {\varGamma \gamma }} \right. } \gamma } - {{\left( {{\varGamma \mathord{\left/ {\vphantom {\varGamma \gamma }} \right. } \gamma }} \right)}^2}} $\end{document}. On the contrary, in the OU noise environment, no information about backflow is obtained, thereby leading the value of the quantum non-local correlation test to increase with evolution time increasing. In most of AD and OU noise environments, there exists a specific maximum evolution time \begin{document}$\gamma {t_{\max }}$\end{document} in which successful quantum non-local correlation testing can be conducted. This maximum evolution time \begin{document}$\gamma {t_{\max }}$\end{document} shows a nonlinear variation with fidelity increasing and an inverse variation with \begin{document}$\varGamma /\gamma $\end{document} parameter increasing. In comparison, the maximum evolution time for successful quantum non-local correlation testing in the OU noise environment exceeds that in the AD environment under the same conditions, indicating that the AD environment exerts a more pronounced weakening effect on the quantum non-local correlation properties of the Werner state."> - 必威体育下载
