In page 6, Eq. (5) should be changed to

\begin{array}{}\text{(5)}& \begin{array}{cc}\mathrm{CNOT}=\hfill & {\mathrm{e}}^{-\mathrm{i}\delta }{R}_y^2\left({\displaystyle \frac{\pi }{2}}\right)R_{zizj}\left(\pi \right)R_{-z}^1\left({\displaystyle \frac{\pi }{2}}\right)\hfill \\ & \cdot R_{-z}^2\left({\displaystyle \frac{\pi }{2}}\right)R_{-y}^2\left({\displaystyle \frac{\pi }{2}}\right)\hfill \end{array}\end{array}
