Function sGate

Source 
pub unsafe extern "C" fn sGate(qureg: Qureg, targetQubit: c_int)
Expand description

Apply the single-qubit S gate. This is a rotation of \f$\pi/2\f$ around the Z-axis on the Bloch sphere, or the unitary: \f[ \begin{pmatrix} 1 & 0 \ 0 & i \end{pmatrix} \f] with circuit diagram: @htmlonly
