If Inflation is modelled by a field - is this a classical field or a quantum field? If classical are there good reasons not to quantise it? What are the implications of such a quantisation?

It is assumed that inflation, both the early and the present one, can be modelled by one or more inflaton fields. These are quantum fields and the quanta of these fields correspond to (at present not directly experimentally observed) particles. – Dilaton Feb 12 '13 at 13:09
It needs to be quantized to have introduce fluctuations in the model. – Vibert Feb 12 '13 at 14:16
