A new preprint argues quantum mechanics may not describe novel physics but instead emerges from formalizing measurement within an algebraic framework, challenging traditional interpretations. Author Marcello Poletti presents a philosophical dialogue suggesting quantum principles could be derived purely from observational constraints, without relying on atomic-scale quantum properties. The paper posits that classical physics, when accounting for measurement limitations and context, can reproduce core quantum structures like superposition and entanglement. This "logical necessity" approach implies quantum mechanics might be an inevitable framework for any theory incorporating measurement, not a radical departure from classical physics. The work bridges quantum physics and philosophy, proposing that foundational quantum rules arise from how observers interact with systems, not inherent particle behaviors.

Quantum Physics arXiv:2601.02419 (quant-ph) [Submitted on 3 Jan 2026] Title:How Alice, long before her time, derived the principles of quantum mechanics Authors:Marcello Poletti View a PDF of the paper titled How Alice, long before her time, derived the principles of quantum mechanics, by Marcello Poletti View PDF HTML (experimental) Abstract:This philosophical dialogue explores the idea that the foundational principles of quantum mechanics need not be interpreted as describing a new physics, but may instead arise from the logical necessity of formalising the act of measurement within a coherent algebraic framework. By pushing this perspective to its extreme, the dialogue argues that the core structures of quantum mechanics can be derived independently of any specifically quantum properties of atomic particles, and can be formulated within an otherwise classical theory once limitations of observability and measurement context are taken seriously.
