A Potentiality and Conceptuality Interpretation of Quantum Physics (1005.3767v1)

Abstract: We elaborate on a new interpretation of quantum mechanics which we introduced recently. The main hypothesis of this new interpretation is that quantum particles are entities interacting with matter conceptually, which means that pieces of matter function as interfaces for the conceptual content carried by the quantum particles. We explain how our interpretation was inspired by our earlier analysis of non-locality as non-spatiality and a specific interpretation of quantum potentiality, which we illustrate by means of the example of two interconnected vessels of water. We show by means of this example that philosophical realism is not in contradiction with the recent findings with respect to Leggett's inequalities and their violations. We explain our recent work on using the quantum formalism to model human concepts and their combinations and how this has given rise to the foundational ideas of our new quantum interpretation. We analyze the equivalence of meaning in the realm of human concepts and coherence in the realm of quantum particles, and how the duality of abstract and concrete leads naturally to a Heisenberg uncertainty relation. We illustrate the role played by interference and entanglement and show how the new interpretation explains the problems related to identity and individuality in quantum mechanics. We put forward a possible scenario for the emergence of the reality of macroscopic objects.

A Conceptual Framework for Quantum Mechanics

This paper by Diederik Aerts proposes a novel interpretation of quantum mechanics through a conceptual lens where quantum particles interact with matter similarly to how concepts interact within human cognition. Here, quantum entities are not viewed as traditional particles or waves but as abstractions that only localize upon measurement. This interpretational shift arises from parallels drawn between quantum formalism and models of human cognition, offering an interesting landscape for discussing foundational quantum phenomena such as non-locality and entanglement.

Interpretation of Quantum Particles as Conceptual Entities

Aerts suggests that quantum particles can be conceived as conceptual entities that only concretize during interaction with matter. This view is partially inspired by violations of Bell's inequalities, which suggest non-local correlations that cannot be explained by classical physics. The paper aligns quantum potentiality and interference patterns with conceptual processes found in cognitive models, where abstract concepts manifest specific states based on context.

Aerts uses an illustrative example of interconnected water vessels to demonstrate the potentiality approach. Just as the state of water in two vessels is only determined by a measuring action, quantum states are equally potential until actualized through interaction. This interpretation defies the traditional view of particles having determined properties prior to measurement, dovetailing with the philosophical implications of quantum mechanics where locality and realism are challenged by phenomena like Leggett’s inequalities.

Conceptual Meaning and Quantum Coherence

An intriguing element of Aerts' proposal is the parallel drawn between "meaning" in human cognitive processes and "coherence" in quantum interactions. Just as concepts acquire specific meanings in varying contexts, quantum entities acquire specific physical properties upon observation, dictated by the system's coherence. This coherence, a fundamental aspect of quantum interactions, further relates to concepts' context-dependent nature, providing a seamless transition from conceptual to physical interaction patterns.

Aerts' interpretation implies that space-time emerges as a secondary framework, much like how semantic environments manifest around cognitive concepts. The proposition effectively places quantum mechanics in a domain not inherently bound by classical space-time, turning micro-realities into potentially abstract constructs that become concrete upon measurement.

Implications for Identity and Individuality in Quantum Systems

The paper explores the identity and individuality of quantum particles, an issue at the crossroads of quantum statistics and the nature of quantum states. Aerts correlates the identity problem of quantum entities with the nature of concepts in cognitive processes, where individuality emerges gradually as entities become more localized. This correlation extends to explaining phenomena like Bose-Einstein statistics, attributing their origin to the abstract quality of quantum entities, unlike macroscopic objects that are traditionally perceived as distinct individuals.

Future Directions and Theoretical Implications

Aerts' interpretation opens several pathways for future research. It challenges researchers to reconsider the foundations of quantum mechanics, encouraging exploration beyond traditional object-centric paradigms. Future work could potentially bridge cognitive science methodologies with quantum theory, fostering interdisciplinary collaborations that explore quantum mechanics through the lens of conceptual thought patterns.

This interpretation has broad implications for understanding quantum reality, suggesting that the emergent nature of space-time might be intricately linked with the cognitive dynamics mirrored at the quantum level. The framework fosters an enriched dialogue between the foundational problems of quantum physics and complex systems' behavior, possibly inspiring innovative experimental inquiries and theoretical advancements across physics, philosophy, and cognitive science.

In conclusion, the conceptual interpretation of quantum mechanics presented in this paper promotes a paradigm where quantum particles are seen as inherently abstract entities. This approach offers a novel viewpoint that aligns with current experimental anomalies and philosophical debates, inviting further scrutiny into the nature of quantum reality and its foundational principles.
