deltakit.circuit.gates.YCX#

class deltakit.circuit.gates.YCX(control: UT | T, target: VT | T, *, tag: str | None = None)#

Bases: ControlledGate[Qubit[T], Qubit[T]]

The Y-controlled X gate. First qubit is the control, second qubit is the target. Applies an X gate to the target if the control is in the |-i> state.

Notes

Negates the amplitude of the |-i,-> state.

Stabilizer Generators:
X_ -> +XX
Z_ -> +ZX
_X -> +_X
_Z -> +YZ
Unitary Matrix:
\[\begin{split}\frac{1}{2} \begin{pmatrix} 1 & -i & 1 & i \\ i & 1 & -i & 1 \\ 1 & i & 1 & -i \\ -i & 1 & i & 1 \end{pmatrix}\end{split}\]
