An overview of the conceptuality interpretation of quantum mechanics is presented, along with an explanation of how it sheds light on key quantum and relativistic phenomena. In particular, we show how the interpretation clarifies Heisenberg's uncertainty principle, wave function-based and entanglement-based non-locality, interference effects resulting from the superposition principle, delayed choice experiments, quantum measurements, the mechanism of quantization, the reason why entities can establish entanglement bonds and the statistical behaviour of indistinguishable entities. We further argue that the interpretation can also elucidate relativistic effects, focusing on time dilation. Finally, we suggest that it can provide a novel and challenging perspective on evolution. This article is the second in a two-part series devoted to exploring this promising approach to reality. The first part, which serves as a companion to this discussion, outlines the intellectual trajectory leading from the first applications of quantum notions to human cognition to the bold rethinking suggested by the conceptuality interpretation.This article is part of the theme issue 'Quantum theory and topology in models of decision making (Part 1)'.

The conceptuality interpretation of quantum mechanics proposes that quantum entities have a conceptual nature, interacting with the material world through processes that are the physical counterpart of the meaning-based processes, which typically occur in human cognition. This interpretation emerged from the early developments in quantum cognition , a field that uses quantum mathematics to model human cognitive activity. It benefited from the specific approach taken by the Brussels research group , modelling concepts themselves as quantum entities and minds as measuring apparatus. The article sketches the essential steps of the intellectual journey, going from the first applications of quantum notions and formalisms to human cognition to the proposal of a potentially groundbreaking interpretation of quantum mechanics, offering profound explanations for major quantum phenomena. This was done by drawing numerous parallels with the human conceptual domain and suggesting the existence of a level of cognitive activity that would underlie our physical reality. This means that an increased cross-fertilization between the conceptuality interpretation and quantum cognition is to be expected in the future, both of which are synergistic in furthering our understanding of the nature of reality. This is the first part of a two-part article. In the second part, which can be read independently of the first, the successes of the interpretation will be described in a more systematic way, providing a brief overview of what has been achieved so far.

The conceptuality interpretation, proposed by Diederik Aerts in 2009, is presented here as a possible theoretical perspective for achieving a unified understanding of many fundamental aspects of quantum mechanics and relativity. After discussing the notion of reality and the role of choice and possibility in the construction of the real, we note how the interpretation emerges from the successes of quantum cognition, and show how it allows us to reinterpret phenomena and experiments such as the double-slit experiment, quantum erasure, entanglement, Bose–Einstein condensation, and the measurement problem by assigning a central role to dynamics governed by meaning, within a pancognitivist perspective. It is further suggested that the metric of relativistic spacetime can also be coherently understood using the same interpretive key. Quantum mechanics and relativity would thus find, in the conceptuality interpretation, an ontological and foundational framework capable of making them not only more intelligible but, in some respects, even intuitive. The price to be paid for this explanatory advantage, however, is that we must relinquish the idea that we live in a world populated primarily by spatiotemporal entities, and instead conceive of reality as a fundamentally cognitive-conceptual structure, in which every interaction ultimately takes the form of a communication.
Since its inception, many physicists have seen in quantum mechanics the possibility, if not the necessity, of bringing cognitive aspects into the play, which were instead absent, or unnoticed, in the previous classical theories. In this article, we outline the path that led us to support the hypothesis that our physical reality is fundamentally conceptual-like and cognitivistic-like. However, contrary to the 'abstract ego hypothesis' introduced by John von Neumann and further explored, in more recent times, by Henry Stapp, our approach does not rely on the measurement problem as expressing a possible 'gap in physical causation', which would point to a reality lying beyond the mind-matter distinction. On the contrary, in our approach the measurement problem is considered to be essentially solved, at least for what concerns the origin of quantum probabilities, which we have reasons to believe they would be epistemic. Our conclusion that conceptuality and cognition would be an integral part of all physical processes comes instead from the observation of the striking similarities between the non-spatial behavior of the quantum micro-physical entities and that of the human concepts. This gave birth to a new interpretation of quantum mechanics, called the 'conceptualistic interpretation', currently under investigation within our group in Brussels.
The emergence of quantum computing has prompted researchers to examine potential parallels between quantum mechanical principles and human cognitive processes. This article explores the theoretical framework of quantum cognition, examining how concepts from quantum mechanics, including superposition, entanglement, and measurement, might inform our understanding of human decision-making, memory, and consciousness. While quantum computing operates on fundamentally different physical principles than biological neural networks, the mathematical formalisms of quantum mechanics offer novel perspectives on cognitive phenomena that classical probability theory struggles to explain. This review critically examines the current state of quantum cognition research, its applications in computational modeling, and the ongoing debates regarding the validity of quantum mechanical analogies in psychological theory. The analysis reveals both promising theoretical insights and significant limitations in applying quantum principles to human cognition, highlighting the need for empirical validation and careful distinction between mathematical analogy and physical reality.
Quantum mechanics, a cornerstone of modern physics, elucidates the behavior of particles at the most fundamental level. This paper delves into the foundational aspects and diverse interpretations of quantum mechanics, shedding light on its enigmatic principles and implications. Beginning with a comprehensive overview of the mathematical framework underlying quantum mechanics, including wave functions, operators, and probabilistic interpretations, the study explores key foundational principles such as superposition, uncertainty, and entanglement. Moreover, it critically examines various interpretations of quantum mechanics, including the Copenhagen interpretation, many-worlds interpretation, and pilot-wave theory, elucidating their philosophical underpinnings and empirical consequences. Through a synthesis of theoretical analysis and empirical evidence, this paper navigates the intricate landscape of quantum mechanics, offering insights into its profound implications for our understanding of reality.
Quantum mechanics is a solidly founded mathematical theory, but it has yet to be explained in first conceptual principles. The most obvious aberration to explanation that quantum mechanics has is interference and coherence. We simply do not understand why the preparation of a quantum mechanical system must not allow knowledge of path in order to display interference effects. We present the first principles of the information interpretation which provide a proper conceptual foundation of quantum mechanics and also lead to an explanation of interference and coherence. The Information Interpretation In the history of the information interpretation of quantum mechanics there are many authors 1,2,3 whom argued that quantum mechanical systems are information, but these presentations of the interpretation have not been able to fully explain the demands of coherence and interference. We argue here that the other interpretations have lacked a “second principle ” that could properly clarify the issue. Specifically, they have lacked a principle that much like the principle of relativity theory is founded on a reasoning of consistency of all perspectives. The earliest of interpretations would all have presented the same underlying argument, that quantum mechanical systems are information, and some formalize this in the manner of truth value to proposition.
