Operational protocols cannot certify classicality Open
The existence and practical utility of operational protocols that certify entanglement raises the question of whether operational protocols exist that certify the absence of entanglement, i.e. that certify separability. We show, within a p…

Temporal depth in a coherent self and in depersonalization: theoretical model Open
Multiple theoretical models of dissociative experiences have been formulated over the last century. These theories are clinically useful; however, it remains unclear if common factors exist in various pathways leading to an onset of dissoc…

Life, its origin, and its distribution: a perspective from the Conway-Kochen Theorem and the Free Energy Principle Open
We argue here that the Origin of Life (OOL) problem is not just a chemistry problem but is also, and primarily, a cognitive science problem. When interpreted through the lens of the Conway-Kochen theorem and the Free Energy Principle, cont…

Whether a quantum computation employs nonlocal resources is operationally undecidable Open
Computational complexity characterizes the usage of spatial and temporal resources by computational processes. In the classical theory of computation, e.g. in the Turing Machine model, computational processes employ only local space and ti…

How do inner screens enable imaginative experience? Applying the free-energy principle directly to the study of conscious experience Open
This paper examines the constraints that the free-energy principle (FEP) places on possible model of consciousness, particularly models of attentional control and imaginative experiences, including episodic memory and planning. We first re…

ER = EPR is an operational theorem Open
We show that in the operational setting of a two-agent, local operations, classical communication (LOCC) protocol, Alice and Bob cannot operationally distinguish monogamous entanglement from a topological identification of points in their …

Nash Equilibria and Undecidability in Generic Physical Interactions—A Free Energy Perspective Open
We start from the fundamental premise that any physical interaction can be interpreted as a game. To demonstrate this, we draw upon the free energy principle and the theory of quantum reference frames. In this way, we place the game-theore…

Making the Thermodynamic Cost of Active Inference Explicit Open
When describing Active Inference Agents (AIAs), the term “energy” can have two distinct meanings. One is the energy that is utilized by the AIA (e.g., electrical energy or chemical energy). The second meaning is so-called Variational Free …

Search for Entanglement between Spatially Separated Living Systems: Experiment Design, Results, and Lessons Learned Open
Statistically significant violations of the Clauser–Horne–Shimony–Holt (CHSH) inequality are the “gold standard” test for quantum entanglement between spatially separated systems. Here, we report an experimental design that implements a CH…

Communication protocols and QECC from the perspective of TQFT, Part II: QECCs as spacetimes Open
Topological quantum field theories (TQFTs) provide a general, minimal-assumption language for describing quantum-state preparation and measurement. They therefore provide a general language in which to express multi-agent communication pro…

Principled Limitations on Self-Representation for Generic Physical Systems Open
The ideas of self-observation and self-representation, and the concomitant idea of self-control, pervade both the cognitive and life sciences, arising in domains as diverse as immunology and robotics. Here, we ask in a very general way whe…

Federated inference and belief sharing Open
This paper concerns the distributed intelligence or federated inference that emerges under belief-sharing among agents who share a common world-and world model. Imagine, for example, several animals keeping a lookout for predators. Their c…

Steps towards a minimal unifying model of consciousness: An integration of models of consciousness based on the free energy principle Open
This paper aims to assess whether the recently proposed "inner screen model" of consciousness that follows from the free-energy principle (FEP) can be regarded as a minimal unifying model (MUM) of consciousness, thereby providing a common …

A Variational Synthesis of Evolutionary and Developmental Dynamics Open
This paper introduces a variational formulation of natural selection, paying special attention to the nature of ‘things’ and the way that different ‘kinds’ of ‘things’ are individuated from—and influence—each other. We use the Bayesian mec…

The inner screen model of consciousness: applying the free energy principle directly to the study of conscious experience Open
This paper presents a model of consciousness that follows directly from the free- energy principle (FEP). We first rehearse the classical and quantum formulations of the FEP. In particular, we consider the “inner screen hypothesis” that fo…

Separability, Contextuality, and the Quantum Frame Problem Open
We study the relationship between assumptions of state separability and both preparation and measurement contextuality, and the relationship of both of these to the frame problem, the problem of predicting what does not change in consequen…

Constructing Condensed Memories in Functorial Time Open
If episodic memory is constructive, experienced time is also a construct. We develop an event-based formalism that replaces the traditional objective, agent-independent notion of time with a constructive, agent-dependent notion of time. We…

The free energy principle induces neuromorphic development Open
We show how any finite physical system with morphological, i.e. three-dimensional embedding or shape, degrees of freedom and locally limited free energy will, under the constraints of the free energy principle, evolve over time towards a n…
