Subquantum detection theory—SDT

We show that the cornerstone of QM—Bornʹs rule—can be obtained from “subquantum detection theory” (SDT). This detection theory is based on purely classical field model for “quantum particles”. Electrons, photons, etc., neutrons are represented as classical waves fluctuating on a very fine time scale, constituting subquantum random fields. A crucial point is that SDT not only reproduce the quantum probabilities for detection, but it provides a possibility to go beyond QM, cf. [Th.M. Nieuwenhuizen, B. Mehmani, V. Spicka, M.J. Aghdami, A.A.Yu. Khrennikov (Eds.), Beyond the Quantum, WSP, Singapore, 2007]. We extend SDT by modelling measurements with the aid of detectors which are sensitive to nonquadratic influence of the subquantum random field. The difference between probabilistic predictions of QM and SDT is estimated.
