) -> Union[bool, NotImplementedType]:
    """Handles the act_on protocol fallback implementation.
    Args:
        action: A gate, operation, or other to act on.
        qubits: The applicable qubits if a gate is passed as the action.
        allow_decompose: Flag to allow decomposition.
    Returns:
        True if the fallback applies, else NotImplemented."""
