qat.lang.X

qat.lang.X

Definition of the \(X\) gate (of arity \(1\)). This gate is part of the default gate set of myQLM and is defined in the default gate set default_gate_set().

Apply gate

from qat.lang import qrout, X

@qrout
def circ():
    X(0)

Control gate

from qat.lang import qrout, X

@qrout
def ctrl_circ():
    X.ctrl()(0, 1)

Multi-controlled gate

from qat.lang import qrout, X

@qrout
def multi_ctrl_circ():
    X.ctrl(2)(0, 1, 2)

Reverse gate

from qat.lang import qrout, X

@qrout
def reversed_circ():
    X.dag()(0)

This \(X\) gate is defined by:

\[\begin{split}\begin{vmatrix} 0 & 1 \\ 1 & 0 \\ \end{vmatrix}\end{split}\]
