Nonlocality - The party may be over

TL;DR

This paper argues that spontaneous parametric processes are better understood as amplifications of the electromagnetic zeropoint field, challenging traditional quantum optics views and supporting a local, zeropoint-field-based explanation of entanglement.

Contribution

It introduces the concept of Spontaneous Parametric Up Conversion, providing evidence for a local zeropoint-field model over the standard nonlocal quantum optics theory.

Findings

Existence of Spontaneous Parametric Up Conversion demonstrated

Supports local zeropoint-field interpretation of optical phenomena

Challenges the nonlocality assumption in quantum optics

Abstract

We demonstrate that the phenomenon known as Spontaneous Parametric Down Conversion is really an amplification, in a nonlinear crystal pumped by a laser, of certain pairs of modes of the electromagnetic zeropoint field. The demonstration is achieved by showing the existence of a related phenomenon, Spontaneous Parametric Up Conversion. This phenomenon, once observed, will cast doubt on the quantum-optical theory, which treats photons as the elementary objects of the light field. It will also lend greater credibility to the zeropoint-field description of optical entanglement phenomena. That description is based on the unquantized light field and is consistently local, in contrast with the nonlocal description of Quantum Optics.
