\begin{document}$C$\end{document} at the last moment \begin{document}$\tau$\end{document} is studied in detail. The results show that on the whole, \begin{document}$C$\end{document} first increases from zero to a maximal value with \begin{document}$\tau$\end{document} increasing, then decreases, and finally it approaches to zero. At first, the system is in a pure state and \begin{document}$C=0$\end{document}. Finally, the system is in a maximally mixed state due to the interaction with the environment and \begin{document}$C=0$\end{document} again. When the number of measurements \begin{document}$N$\end{document} is relatively small, \begin{document}$C$\end{document} fluctuates with \begin{document}$\tau$\end{document} increasing, but when \begin{document}$N$\end{document} is relatively large, the fluctuations disappear. Due to the quantum Zeno effect, as \begin{document}$N$\end{document} is larger, the variation of \begin{document}$C$\end{document} with \begin{document}$\tau$\end{document} is similar to that for the case of no intermediated measurement. Because of the quantum superposition principle, uncertainty principle, and quantum collapse, quantum measurement can disturb the system, so quantum statistical complexity \begin{document}$C$\end{document} exhibits a complex behavior. In the quantum realm, the complexity of a system can be transformed into a resource. The quantum state needs creating, operating, or measuring. Therefore, all our results provide a theoretical reference for the optimal controlling of quantum information process and condensed matter physics. At the same time, the number of the degrees of freedom is two for the damped and linearly driven two-level system, so this system is simple and easy to study. The complexity of such a system can be tailored by properly tuning the driving strength. Therefore, the model can be used as a typical example to study the quantum statistical complexity."> - 必威体育下载
