deltakit.circuit.gates.SQRT_ZZ_DAG

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

Bases: SymmetricTwoQubitGate[T]

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

Notes

Stabilizer Generators:

X_ -> -YZ

Z_ -> +Z_

_X -> -ZY

_Z -> +_Z

Unitary Matrix:

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

Methods

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