SXdgGate#
- class qiskit.circuit.library.SXdgGate(label=None)[소스]#
기반 클래스:
GateThe inverse single-qubit Sqrt(X) gate.
Can be applied to a
QuantumCircuitwith thesxdg()method.\[\begin{split}\sqrt{X}^{\dagger} = \frac{1}{2} \begin{pmatrix} 1 - i & 1 + i \\ 1 + i & 1 - i \end{pmatrix}\end{split}\]참고
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.
