Unobservable Potentials to Explain a Quantum Eraser and a Delayed-Choice Experiment

TL;DR

This paper proposes a novel explanation for quantum eraser and delayed-choice experiments using unobservable potentials, challenging the necessity of quantum-superposition states and suggesting long-range correlations beyond causality.

Contribution

It introduces unobservable potentials as an alternative to quantum-superposition states for explaining quantum phenomena, providing a new theoretical perspective.

Findings

Quantum eraser explained without superposition states

Delayed-choice experiment interpreted via interference with unobservable potentials

Suggests long-range correlations beyond traditional causality

Abstract

We present a new explanation for a quantum eraser. Mathematical description of the traditional explanation needs quantum-superposition states. However, the phenomenon can be explained without quantum-superposition states by introducing unobservable potentials which can be identified as an indefinite metric vector. In addition, a delayed choice experiment can also be explained by the interference between the photons and unobservable potentials, which seems like an unreal long-range correlation beyond the causality.
