add(noise: TNoise) → None

add(noise: TNoise, *, qubits: list[Qubit]) → None

add(noise: TNoise, *, gate: GateType) → None

Attach a noise source or parameter perturbation to the model.

Parámetros:

• noise (Noise | ParameterPerturbation) – The noise or parameter perturbation instance to attach.

• qubits (list[int] | None) – Target qubit index or indices for per-qubit noise attachments.

• gate (type[Gate] | None) – Target gate type for per-gate noise or perturbation attachments.

• parameter (str | None) – Target parameter name for perturbation attachments.

Muestra:

ValueError – If the noise/perturbation does not allow the inferred scope.
