TGate

class TGate(label=None)[fuente]

Bases: Gate

Single qubit T gate (Z**0.25).

It induces a \(\pi/4\) phase, and is sometimes called the pi/8 gate (because of how the RZ(pi/4) matrix looks like).

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

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

Matrix Representation:

\[\begin{split}T = \begin{pmatrix} 1 & 0 \\ 0 & e^{i\pi/4} \end{pmatrix}\end{split}\]

Circuit symbol:

     ┌───┐
q_0: ┤ T ├
     └───┘

Equivalent to a \(\pi/4\) radian rotation about the Z axis.
