SXdgGate

class SXdgGate(label=None)

Bases: qiskit.circuit.gate.Gate

The inverse single-qubit Sqrt(X) gate.

\begin{split}\sqrt{X}^{\dagger} = \frac{1}{2} \begin{pmatrix} 1 - i & 1 + i \\ 1 + i & 1 - i \end{pmatrix}\end{split}

Note

A global phase difference exists between the definitions of $RX(-\pi/2)$ and $\sqrt{X}^{\dagger}$ .

\begin{split}RX(-\pi/2) = \frac{1}{\sqrt{2}} \begin{pmatrix} 1 & i \\ i & 1 \end{pmatrix} = e^{-i pi/4} \sqrt{X}^{\dagger}\end{split}

Create new SXdg gate.
