Relational Quantum Mechanics is about Facts, not States: A reply to Pienaar and Brukner

TL;DR

This paper defends the relational interpretation of quantum mechanics against recent objections, clarifying its principles and reinforcing its viability through detailed responses.

Contribution

It provides a detailed rebuttal to critiques of the relational interpretation, strengthening its conceptual foundation and addressing misconceptions.

Findings

Objections to the relational interpretation are addressed and refuted.

The clarifications reinforce the interpretation's consistency and viability.

The paper enhances understanding of facts versus states in quantum mechanics.

Abstract

In recent works, \v{C}aslav Brukner and Jacques Pienaar have raised interesting objections to the relational interpretation of quantum mechanics. We answer these objections in detail and show that, far from questioning the viability of the interpretation, they sharpen and clarify it.
