Signature

def spp(b: GraphRepresentation, paulis: list[tuple[Literal['X', 'Y', 'Z'], int]], dagger: bool = False) -> None

Apply exp(-i pi/4 P) (up to global phase) for a Pauli product P.

Phases the -1 eigenspace of P by i (or -i if dagger). For a single qubit, SPP Z0 is the S gate and SPP_DAG Z0 is S_DAG.

Parameters

Name	Type	Default	Description
`b`	`GraphRepresentation`	required	The graph representation to modify.
`paulis`	`list[tuple[Literal['X', 'Y', 'Z'], int]]`	required	List of (pauli_type, qubit) pairs defining the Pauli product P.
`dagger`	`bool`	`False`	If True, apply exp(+i pi/4 P) (phase by -i) instead.
