The Hidden-Measurement Formalism: Quantum Mechanics as a Consequence of Fluctuations on the Measurement

We expose a formalism, that we have called the’ hidden measurement formalism’, where the quantum structure is due to the presence of ‘fluctuations’ on the interaction between the system and the measurement apparatus. In this formalism the quantum mechanical probabilities are not ontological but arrise as a consequence of ‘lack of knowledge’ about this interaction. We study the quantum classical limit and the EPR problem in the light of this explanation.
