deltakit.circuit.gates.ISWAP_DAG

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

Bases: SymmetricTwoQubitGate[T]

Swaps two qubits and phases the -1 eigenspace of the ZZ observable by -i. Equivalent to SWAP then CZ then S_DAG on both targets.

Notes

Stabilizer Generators:

X_ -> -ZY

Z_ -> +_Z

_X -> -YZ

_Z -> +Z_

Unitary Matrix:

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

Methods

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