qat.lang.vendors.GPi

qat.lang.vendors.GPi

Definition of the \(GPi\) gate (of arity \(1\)). This gate is not included in the default gate set of myQLM, but in the gate set ionq_gate_set().

Apply gate

from qat.lang import qrout
from qat.lang.vendors import GPi

@qrout
def circ(alpha):
    GPi(alpha)(0)

Control gate

from qat.lang import qrout
from qat.lang.vendors import GPi

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

Multi-controlled gate

from qat.lang import qrout
from qat.lang.vendors import GPi

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

Reverse gate

from qat.lang import qrout
from qat.lang.vendors import GPi

@qrout
def reversed_circ(alpha):
    GPi(alpha).dag()(0)

This \(GPi\) gate is defined by:

\[\begin{split}\forall \phi \in\rm I\!R: \begin{vmatrix} 0 & e^{-i\phi} \\ e^{i\phi} & 0 \\ \end{vmatrix}\end{split}\]
