The concept of a “system” is foundational to physics, but the question of how observers identify systems is seldom addressed. Classical thermodynamics restricts observers to finite, finite-resolution observations with which to identify the systems on which “pointer state” measurements are to be made. It is shown that system identification is at best approximate, even in a finite world, and that violations of the Leggett–Garg and Bell/CHSH (Clauser-Horne-Shimony-Holt) inequalities emerge…

Representing Measurement as a Thermodynamic Symmetry Breaking
This work employs category-theoretic methods, particularly the theory of classifiers, to characterize the full interaction between observer and world in terms of information and resource flows and shows that breaking these symmetries induces decoherence, contextuality, and measurement-associated disturbance of the system of interest.

Timelessness Strictly inside the Quantum Realm
It is proposed that a label of timelessness offers clues for rendering a Copenhagen-type interpretation of quantum physics more “realistic” and acceptable by providing a coarse but viable link from the fundamental quantum realm to the classical world which humans directly experience.
Equivalence of the Frame and Halting Problems
It is proved that the open-domain Frame Problem is equivalent to the Halting Problem and is therefore undecidable, and reformulate the Frame Problem as a quantum decision problem, and shows that it is undECidable by any finite quantum computer.
Information flow in context-dependent hierarchical Bayesian inference
A novel and general approach to the characterisation of contextuality using the techniques of Chu spaces and Channel Theory viewed as general theories of information flow is introduced, which relates contextuality to the Frame Problem, another way of characterising a fundamental limitation on the observational and inferential capabilities of finite agents.
Reference Frame Induced Symmetry Breaking on Holographic Screens
It is shown that when an interaction between finite quantum systems in a separable joint state is represented as a measurement, the quantum reference frames deployed to identify systems and pick out their pointer states induce decoherence, breaking the symmetry of the holographic encoding in an observer-relative way.
How Do Living Systems Create Meaning?
The notion of “meaning” as it applies to living systems is reviewed, and the question of how living systems create meaning unifies the biological and cognitive sciences across both organizational and temporal scales is argued.
Sharing Nonfungible Information Requires Shared Nonfungible Information
We show that sharing a quantum reference frame requires sharing measurement operators that identify the reference frame in addition to operators that measure its state. Observers restricted to finite


A simple explanation of Born's rule
Identifying the property of the world that enforces the Born rule is a longstanding problem in physics. We prove that in any physical theory that assigns probabilities to the outcomes of ideal
A model-theoretic interpretation of environment-induced superselection
Einselection is reformulated in terms of positive operator-valued measures acting on a global quantum state and it is shown that this reformulation enables a natural interpretation of apparently classical systems as virtual machines that requires no assumptions beyond those of classical computer science.
Environment-induced superselection rules
We show how the correlations of a quantum system with other quantum systems may cause one of its observables to behave in a classical manner. In particular, "reduction of the wave packet," postulated
If Physics Is an Information Science, What Is an Observer?
The consequences of replacing an informationally-impoverished observer with an observer that satisfies the requirements of classical automata theory is investigated, showing that with reasonable assumptions about the physical dynamics of information channels, the observations recorded by such an observer will display the typical characteristics predicted by quantum theory.
Relational quantum mechanics
I suggest that the common unease with taking quantum mechanics as a fundamental description of nature (the “measurement problem”) could derive from the use of an incorrect notion, as the unease with

Evidence for the epistemic view of quantum states: A toy theory
We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in a
Quantum Darwinism
Quantum Darwinism describes the proliferation, in the environment, of multiple records of selected states of a quantum system. It explains how the fragility of a state of a single quantum system can
No return to classical reality
This article reviews results on the fundamental phenomena of quantum theory that cannot be understood in classical terms and describes some aspects of quantum physics that can never admit a classical understanding – the intrinsically quantum mechanical aspects of nature.
Decoherence, einselection, and the quantum origins of the classical
as quantum engineering. In the past two decades it has become increasingly clear that many (perhaps all) of the symptoms of classicality can be induced in quantum systems by their environments. Thus
