deltakit.circuit.gates.CXSWAP

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

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

A combination CX-and-SWAP gate. This gate is kak-equivalent to the ISWAP gate, but preserves X/Z noise bias. Equivalent to CNOT from target to control, immediately followed by another CNOT from control to target.

Notes

Stabilizer Generators:

X_ -> XX

Z_ -> _Z

_X -> X_

_Z -> ZZ

Unitary Matrix:

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

Methods

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