 Hence the required gate is $R_x(2\arctan\frac{\beta}{\alpha})$, which in matrix form is $\begin{bmatrix} \alpha & -i\beta \\\ -i\beta & \alpha \end{bmatrix}$.
 This gate turns $|0\rangle = \begin{bmatrix} 1 \\\ 0\end{bmatrix}$ into $\begin{bmatrix} \alpha & -i\beta \\\ -i\beta & \alpha \end{bmatrix} \begin{bmatrix} 1 \\\ 0\end{bmatrix} = \begin{bmatrix} \alpha \\\ -i\beta \end{bmatrix} = \alpha|0\rangle -i\beta|1\rangle$.
