TdgGate

class TdgGate(label=None)

Bases: qiskit.circuit.gate.Gate

Single qubit T-adjoint gate (~Z**0.25).

It induces a $-\pi/4$ phase.

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

Matrix Representation:

\begin{split}Tdg = \begin{pmatrix} 1 & 0 \\ 0 & e^{-i\pi/4} \end{pmatrix}\end{split}

Circuit symbol:

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

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

Create new Tdg gate.
