SGate¶
- class SGate(label=None)[source]¶
Bases:
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.
Can be applied to a
QuantumCircuit
with thes()
method.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.
Methods Defined Here
Return inverse of S (SdgGate).
Raise gate to a power.
