deltakit.circuit.gates.YCY

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

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

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

Notes

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

Stabilizer Generators:

X_ -> +XY

Z_ -> +ZY

_X -> +YX

_Z -> +YZ

Unitary Matrix:

\[\begin{split}\frac{1}{2} \begin{pmatrix} 1 & -i & -i & 1 \\ i & 1 & -1 & -i \\ i & -1 & 1 & -i \\ 1 & i & i & 1 \end{pmatrix}\end{split}\]

Methods

YCY.from_consecutive	Yield an class instance for each pair in a flattened sequence of data.
YCY.stim_targets	Get the stim gate targets which define this operation.
YCY.transform_qubits	Transform this gates's qubits according to the id mapping.
