      Args:
          tape (QuantumTape or QNode or Callable): a quantum circuit.
          stopping_condition (Callable): a function from an operator to a boolean. If ``False``, the operator
              should be decomposed. If an operator cannot be decomposed and is not accepted by ``stopping_condition``,
              a ``DecompositionUndefinedError`` will be raised.
          skip_initial_state_prep=True (bool): If ``True``, the first operator will not be decomposed if it inherits from :class:`~.StatePrepBase`.
          decomposer (Callable): an optional callable that takes an operator and implements the relevant decomposition.
              If None, defaults to using a callable returning ``op.decomposition()`` for any :class:`~.Operator` .
          max_expansion (int): The maximum depth of the expansion.
  
  
      Returns:
          qnode (QNode) or quantum function (Callable) or tuple[List[QuantumTape], function]:
  
          The decomposed circuit. The output type is explained in :func:`qml.transform <pennylane.transform>`.
  
      Raises:
          DecompositionUndefinedError: if an operator is not accepted and does not define a decomposition
  
          DeviceError: If the decomposition enters and infinite loop and raises a ``RecursionError``.
  
      **Example:**
  
      >>> def stopping_condition(obj):
      ...     return obj.name in {"CNOT", "RX", "RZ"}
      >>> tape = qml.tape.QuantumScript([qml.IsingXX(1.2, wires=(0,1))], [qml.expval(qml.PauliZ(0))])
      >>> batch, fn = decompose(tape, stopping_condition)
      >>> batch[0].circuit
      [CNOT(wires=[0, 1]),
      RX(1.2, wires=[0]),
      CNOT(wires=[0, 1]),
      expval(PauliZ(wires=[0]))]
  
      If an operator cannot be decomposed into a supported operation, an error is raised:
  
      >>> decompose(tape, lambda obj: obj.name == "S")
      DeviceError: Operator CNOT(wires=[0, 1]) not supported on device and does not provide a decomposition.
  
      The ``skip_initial_state_prep`` specifies whether or not the device supports state prep operations
      at the beginning of the circuit.
