deltakit.circuit.gates.SQRT_XX_DAG

class deltakit.circuit.gates.SQRT_XX_DAG(operand1: UT | T, operand2: VT | T, *, tag: str | None = None)

Bases: SymmetricTwoQubitGate[T]

Phases the -1 eigenspace of the XX observable by -i.

Notes

Stabilizer Generators:

X_ -> +X_

Z_ -> +YX

_X -> +_X

_Z -> +XY

Unitary Matrix:

\[\begin{split}\frac{1}{2} \begin{pmatrix} 1-i & 0 & 0 & 1+i \\ 0 & 1-i & 1+i & 0 \\ 0 & 1+i & 1-i & 0 \\ 1+i & 0 & 0 & 1-i \end{pmatrix}\end{split}\]

Methods

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