SdgGate

class qiskit.circuit.library.SdgGate(label=None)

Bases: Gate

Single qubit S-adjoint gate (~Z**0.5).

It induces a $-\pi/2$ phase.

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

Can be applied to a QuantumCircuit with the sdg() method.

Matrix Representation:

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

Circuit symbol:

     ┌─────┐
q_0: ┤ Sdg ├
     └─────┘

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

Create new Sdg gate.
