Expand description
Apply the single-qubit T gate. This is a rotation of \f$\pi/4\f$ around the Z-axis on the Bloch sphere, or the unitary: \f[ \begin{pmatrix} 1 & 0 \ 0 & \exp\left(i \frac{\pi}{4}\right) \end{pmatrix} \f] with circuit diagram: \f[ \begin{tikzpicture}[scale=.5] \node[draw=none] at (-3.5, 0) {target};
\draw (-2,0) – (-1, 0); \draw (1, 0) – (2, 0); \draw (-1,-1)–(-1,1)–(1,1)–(1,-1)–cycle; \node[draw=none] at (0, 0) {T}; \end{tikzpicture} \f]
