Stochastic interpretation of quantum mechanics assuming that vacuum fields are real

I review the realistic interpretation of several typically quantum phenomena using a heuristic approach that rests on the assumption that the electromagnetic quantum vacuum is a stochastic field. I include the particle behaviour of light, the photoelectric effect, the hdrogen atom, the Casimir effect, and entanglement in the optical tests of Bell inequalities. The stochastic approach might be formally connected with the standard Hilbert space formalism via the Wigner representation of the field.
