Quantum observer and Kolmogorov complexity: a model that can be tested

TL;DR

This paper proposes a model linking quantum observation with Kolmogorov complexity, suggesting that systems can be objectively identified as elements of reality and proposing experimental tests for quantum observers.

Contribution

It introduces a complexity-based condition for quantum systems to be considered objective elements of reality and suggests feasible experiments to test quantum observation by small systems.

Findings

A complexity criterion for quantum objectivity

Proposal for experimental validation of quantum observers

Insight into observer-system relationships in quantum mechanics

Abstract

Different observers do not have to agree on how they identify a quantum system. We explore a condition based on algorithmic complexity that allows a system to be described as an objective "element of reality". We also suggest an experimental test of the hypothesis that any system, even much smaller than a human being, can be a quantum mechanical observer.
