Totality of Subquantum Nonlocal Correlations

TL;DR

This paper introduces a classical field theory model that predicts universal nonlocal correlations among all quantum systems, attributing these correlations to a common background field, thus offering a classical explanation for quantum nonlocality.

Contribution

It proposes a prequantum classical statistical field theory (PCSFT) that reproduces quantum correlations and predicts nonlocal correlations at the subquantum level for all quantum systems.

Findings

Predicts nonlocal correlations between all prequantum fields

Demonstrates correlations arise from a common background field

Shows correlations exist even for factorizable quantum states

Abstract

In a series of previous papers we developed a purely field model of microphenomena, so called prequantum classical statistical field theory (PCSFT). This model not only reproduces important probabilistic predictions of QM including correlations for entangled systems, but it also gives a possibility to go beyond quantum mechanics (QM), i.e., to make predictions of phenomena which could be observed at the subquantum level. In this paper we discuss one of such predictions - existence of nonlocal correlations between prequantum random fields corresponding to {\it all} quantum systems. (And by PCSFT quantum systems are represented by classical Gaussian random fields and quantum observables by quadratic forms of these fields.) The source of these correlations is the common background field. Thus all prequantum random fields are "entangled", but in the sense of classical signal theory. On one hand, PCSFT demystifies quantum nonlocality by reducing it to nonlocal classical correlations based on the common random background. On the other hand, it demonstrates total generality of such correlations. They exist even for distinguishable quantum systems in factorizable states (by PCSFT terminology - for Gaussian random fields with covariance operators corresponding to factorizable quantum states).
