SGate

class SGate(label=None)

Bases: qiskit.circuit.gate.Gate

Single qubit S gate (Z**0.5).

It induces a $\pi/2$ phase, and is sometimes called the P gate (phase).

This is a Clifford gate and a square-root of Pauli-Z.

Matrix Representation:

\begin{split}S = \begin{pmatrix} 1 & 0 \\ 0 & i \end{pmatrix}\end{split}

Circuit symbol:

     ┌───┐
q_0: ┤ S ├
     └───┘

Equivalent to a $\pi/2$ radian rotation about the Z axis.

Create new S gate.
