On the quantum origin of potentials

TL;DR

This paper explores the idea that observed potentials in quantum systems may partly originate from quantum potentials, challenging the classical-quantum separation and discussing its implications.

Contribution

It investigates the possibility that quantum potentials contribute to observed potentials, offering a new perspective on quantum-classical interactions.

Findings

Quantum potential may account for part of observed potentials

The classical and quantum potentials are inseparable in principle

Implications for interpreting quantum measurements and potentials

Abstract

The dynamics of a quantum particle is governed by its wavefunction, which in turn is determined by the classical potential to which it is subjected. However the wavefunction itself induces a quantum potential, the particle `sees' the sum of the classical and quantum potentials, and there is no way to separate the two. Therefore in principle, part or whole of an observed potential may be attributable to a quantum potential. We examine this possibility and discuss implications.
