Nonlocality at detection and conservation of energy. Was Einstein looking for an "epistemic" interpretation, a "superdeterministic" one, or both?

TL;DR

This paper argues that Einstein's critique of quantum nonlocality overlooked the necessity of nonlocality at detection for energy conservation, linking epistemic interpretations to superdeterminism and refuting certain quantum interpretations.

Contribution

It demonstrates that energy conservation requires nonlocality at detection, challenging epistemic and ontic interpretations and connecting Einstein's epistemicism to superdeterminism.

Findings

Energy conservation implies nonlocality at detection.

Recent experiment refutes epistemic and ontic interpretations.

Einstein's epistemicism entails superdeterminism.

Abstract

In the Solvay conference (1927) Einstein argued against the quantum nonlocal decision at detection on the basis of a simple single-particle experiment, but thereafter he withdrew towards the more complicated 2-particle EPR argument. It has been claimed that Einstein was seeking for an "epistemic interpretation". In the light of a recent experiment I argue that Einstein missed an important point: One cannot have conservation of energy without nonlocality at detection. This experiment refutes also straightforwardly "epistemic" and "ontic" alternatives to quantum theory, and shows that Einstein's "epistemicism" entails "superdeterminism".
