On the Paradox of Quantum Entanglement and the Dual Possibilities of Physical Foundations: Quantum Limitations and Spatial Cognitive Bias

hong li

The unmediated, instantaneous long-range correlation demonstrated by quantum entanglement has been repeatedly confirmed by experiments, yet it forms an irreconcilable logical paradox with humanity’s fundamental understanding of cosmic scale, spatial separation, and cognitive limitations. If entanglement is acknowledged to possess infinite, universal action capacity, it would lead to the extreme conclusion that humans could directly reach the boundaries of the universe and connect with the entire cosmos through microscopic quantum phenomena—a notion entirely at odds with the reality that humanity has yet to escape the solar system and remains largely ignorant of the vast majority of the universe. Through rigorous logical deduction, this paper proposes the only self-consistent dual possibilities: first, quantum entanglement may possess undiscovered physical limitations, with its nonlocal properties effective only within a finite scale; second, modern physics may harbor fundamental cognitive biases regarding the nature of space, the meaning of distance, and the reality of separation, suggesting that space is not an objective, independent foundational physical entity. This paper systematically demonstrates the rationality, self-consistency, and revolutionary implications of these two possibilities for physics and cosmology, offering a novel theoretical framework to resolve the underlying conflict between quantum mechanics and cosmology.

Quantum Information in Neural Systems

Danko Dimchev Georgiev

Identifying the physiological processes in the central nervous system that underlie our conscious experiences has been at the forefront of cognitive neuroscience. While the principles of classical physics were long found to be unaccommodating for a causally effective consciousness, the inherent indeterminism of quantum physics, together with its characteristic dichotomy between quantum states and quantum observables, provides a fertile ground for the physical modeling of consciousness. Here, we utilize the Schrödinger equation, together with the Planck–Einstein relation between energy and frequency, in order to determine the appropriate quantum dynamical timescale of conscious processes. Furthermore, with the help of a simple two-qubit toy model we illustrate the importance of non-zero interaction Hamiltonian for the generation of quantum entanglement and manifestation of observable correlations between different measurement outcomes. Employing a quantitative measure of entanglement based on Schmidt decomposition, we show that quantum evolution governed only by internal Hamiltonians for the individual quantum subsystems preserves quantum coherence of separable initial quantum states, but eliminates the possibility of any interaction and quantum entanglement. The presence of non-zero interaction Hamiltonian, however, allows for decoherence of the individual quantum subsystems along with their mutual interaction and quantum entanglement. The presented results show that quantum coherence of individual subsystems cannot be used for cognitive binding because it is a physical mechanism that leads to separability and non-interaction. In contrast, quantum interactions with their associated decoherence of individual subsystems are instrumental for dynamical changes in the quantum entanglement of the composite quantum state vector and manifested correlations of different observable outcomes. Thus, fast decoherence timescales could assist cognitive binding through quantum entanglement across extensive neural networks in the brain cortex.

Quantum entanglement in physical and cognitive systems: A conceptual analysis and a general representation

Diederik Aerts, Jonito Aerts Arguëlles, Lester Beltran +4 more

Abstract We provide a general description of the phenomenon of entanglement in bipartite systems, as it manifests in micro and macro physical systems, as well as in human cognitive processes. We do so by observing that when genuine coincidence measurements are considered, the violation of the ‘marginal laws’, in addition to the Bell-CHSH inequality, is also to be expected. The situation can be described in the quantum formalism by considering the presence of entanglement not only at the level of the states, but also at the level of the measurements. However, at the “local” level of a specific joint measurement, a description where entanglement is only incorporated in the state remains always possible, by adopting a fine-tuned tensor product representation. But contextual tensor product representations should only be considered when there are good reasons to describe the outcome-states as (non-entangled) product states. This will not in general be true, hence, the entanglement resource will have to generally be allocated both in the states and in the measurements. In view of the numerous violations of the marginal laws observed in physics’ laboratories, it remains unclear to date if entanglement in micro-physical systems is to be understood only as an ‘entanglement of the states’, or also as an ‘entanglement of the measurements’. But even if measurements would also be entangled, the corresponding violation of the marginal laws (also called ‘no-signaling conditions’) would not for this imply that a superluminal communication would be possible.
