“…The fundamental goal of stochastic quantization (Bacciagaluppi, 1999;Belavkin, 2003;de la Peña and Cetto, 1996;Gaioli et al, 1997;Hooft, 1997;Namiki, 1982Namiki, , 2000Olavo, 2000;Torres and Figueiredo, 2003) is to reproduce the whole content of quantum mechanics by means of classical equations subjected to random perturbations. Presently, there remains the controversy about the physical origin of the noise, which is supposed to arise, for instance, from a fluctuating metrics or from fluctuations of the vacuum electromagnetic field.…”
