deltakit.circuit.gates.CZSWAP

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

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

A combination CZ-and-SWAP gate. This gate is kak-equivalent to the ISWAP gate. Equivalent to H on the target qubit, followed by CNOT from target to control, CNOT from control to target, and finally H on the control qubit.

Notes

Stabilizer Generators:

X_ -> ZX

Z_ -> _Z

_X -> XZ

_Z -> Z_

Unitary Matrix:

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