Abstract

The human brain acts as a very efficient parallel classical-quantum communications system relating responses to a multitude of input signals from sensors. However, the mechanisms of the quantum communication channel in the brain remain a mystery. Since matter and energy cannot be teleported, in the sense of transferring from one place to another without passing through intermediate locations, teleportation of quantum states, as the ultimate structure of objects, is possible. Only the structure, information about conformation state, is teleported - the matter stays at the source side and has to be already present at the final location. From this point of view, we consider a new type of network in the brain, based on a unity of classical and quantum neural-astrocyte networks. Matter and energy (classical channel) and classical quantum information travel through neurons, while through the astrocyte-neuron loop travel classical quantum and non-classical quantum information. The new type of network is a synergetic one with quite new energy-information properties compared to classical neuron networks.

A Historical View of the Relation Between Quantum Mechanics and the Brain: A NeuroQuantologic Perspective

Sultan Tarlacı

Over the past decade, discussions of the roles that quantum mechanics might or might not play in the theory of consciousness/mind have become increasingly sharp. One side of this debate stand conventional neuroscientists who assert that brain science must look to the neuron for understanding, and on the other side are certain physicists, suggesting that the rules of quantum theory might influence the dynamics of consciousness/mind. However, consciousness and mind are not separate from matter. Submicroscopic world of the human brain give rise to consciousness, mind. We are never able to make a sharp separation between mind and matter. Thus ultimately there is no “mind” that can be separated from “matter” and no “matter” that can be separated from “mind”. The brain as a mixed physical system composed of the macroscopic neuron system and an additional microscopic system. The former consists of pathway conduction of neural impulses. The latter is assumed to be a quantum mechanical many-body system interacting with the macroscopic neuron system.

Quantum Information Flow in Neuronal Networks

Jincheng Zhang

This paper proposes a novel framework for understanding neuronal information processing, suggesting that quantum entanglement plays a significant role in neural communication, termed "quantum neurons." We introduce a model that incorporates quantum superposition and entanglement to simulate neuronal activity, moving beyond classical neuron models. The core mechanism involves utilizing quantum measurements and feedback loops to process information within this quantum neural network. We demonstrate how entangled states can facilitate information transfer exceeding the limitations of classical models, potentially explaining phenomena like consciousness and intelligence. The theoretical framework presented here offers a fundamentally new perspective on the nature of neuronal computation and provides a basis for future research in quantum neuroscience. The primary mathematical concepts explored include quantum state vectors, measurement operators, and the evolution of entangled systems. Key equations and notation are presented below for clarity.

On the Theoretical Possibility of Quantum Visual Information Transfer to the Human Brain

Vahid Salari, Mohammad Bagher Rahnama, Jack A. Tuszyński

The feasibility of wave function collapse in the human brain has been the subject of vigorous scientific debates since the advent of quantum theory. Scientists like Von Neumann, London, Bauer and Wigner (initially) believed that wave function collapse occurs in the brain or is caused by the mind of the observer. It is a legitimate question to ask how human brain can receive subtle external visual quantum information intact when it must pass through very noisy and complex pathways from the eye to the brain? There are several approaches to investigate information processing in the brain, each of which presents a different set of conclusions. Penrose and Hameroff have hypothesized that there is quantum information processing inside the human brain whose material substrate involves microtubules and consciousness is the result of a collective wavefunction collapse occurring in these structures. Conversely, Tegmark stated that owing to thermal decoherence there cannot be any quantum processing in neurons of the brain and processing in the brain must be classical for cognitive processes. However, Rosa and Faber presented an argument for a middle way which shows that none of the previous authors are completely right and despite the presence of decoherence, it is still possible to consider the brain to be a quantum system. Additionally, Thaheld, has concluded that quantum states of photons do collapse in the human eye and there is no possibility for collapse of visual quantum states in the brain and thus there is no possibility for the quantum state reduction in the brain. In this paper we conclude that if we accept the main essence of the above approaches taken together, each of them can provide a different part of a teleportation mechanism.

The Quantum Mind/Classical Brain Problem

Alfredo Pereira

The quantum theory of mind allows a shift from the Mind/Brain metaphysical problem to the Quantum Mind/Classical Brain scientific problem: how could systematic and coherent quantum processes - assumed to be the physical support of our conscious experiences - occur in a macroscopic system as the brain? I discuss a solution based on a neurobiological model that attributes to quantum computation in intra-neuronal signal-transduction pathways the role of directly supporting phenomenal experience. In this model, quantum coherence is created or prepared by classical mechanisms as recurrent neuronal networks, oscillatory synchrony and gated membrane channels, thus avoiding common theoretical constraints for the existence of quantum communication and computation, as ultra-cold temperatures and quasi-isolation from the environment.

How Can the Visual Quantum Information be Transferred to The Brain Intact, Collapsing There and Causing Consciousness?

Majid Rahnama, Vahid Salari, Jack A. Tuszyński

The main problem which this paper tries to address is whether collapse of the wave function describing the state of a quantum mechanical system occurs, or, rather can occur in the brain of the observer or not. One of the first (relatively) detailed “collapse models” following the original abstract suggestion by von Neumann that collapse occurs in the brain of the observer and is related to consciousness, is the Orch OR model of Penrose and Hameroff. This model was first criticized by Tegmark on the ground that due to decoherence, quantum processing cannot occur in the human brain. This criticism was countered by saying that due to structural shielding, microtubules inside the neurons can be protected against the wet and warm environment inside the brain. Thaheld, however, in a number of papers argued that quantum visual information carried by the photons from the environment cannot reach the brain intact. In other words, the quantum states of the photons would collapse inside the human eye and only classical information would finally reach the brain and hence no collapse and quantum processing in the brain can take place. In this paper we advance a hypothesis that there is the possibility for the quantum states of photons to be transmitted to the brain in a quantum-like manner. Our approach is based on the quantum teleportation mechanism which includes both classical and quantum aspects of information transfer, but the process itself is wholly quantum mechanical.
