The QBIT theory of consciousness: Entropy and qualia

The QBIT Theory of Consciousness: Information, Correlation, and Coherence

The ultimate goal of the QBIT theory is to provide a scientific solution to the problem of consciousness. The theory assumes that qualia (plural for quale) are real physical entities. Each quale is a physical system consisting of qubits bonded together by quantum entanglement. The qubits of a quale are so intimately bonded together that they collectively form a unified whole that is more than (and different from) the sum of its parts. A quale is a highly organized, coherent system. Organization and coherence are manifestations of information. The more the amount of information in a system, the more organized, integrated, and coherent the system is. That is why the QBIT theory suggests that qualia are maximally entangled, maximally coherent systems containing high amounts of information, and extremely low amounts of entropy or uncertainty.

The QBIT Theory: Consciousness from Entangled Qubits

How does the brain generate consciousness? The present paper is an attempt to answer this question from the perspective of the QBIT theory. In sum, the theory argues that the brain has a prior belief (P) about the stimulus that has caused a sensory representation (R) to be created in the brain. When the conditional entropy of P given R becomes less than zero, the brain becomes more than certain about (i.e. becomes conscious of) the stimulus. Conditional entropy can become negative (and thus the brain can become more than certain) only if the brain uses entangled quantum information in its computations. The QBIT theory suggests that, at the most fundamental level, consciousness is nothing but a special kind of entangled information.

Quantum core affect. Color-emotion structure of semantic atom

Psychology suffers from the absence of mathematically-formalized primitives. As a result, conceptual and quantitative studies lack an ontological basis that would situate them in the company of natural sciences. The article addresses this problem by describing a minimal psychic structure, expressed in the algebra of quantum theory. The structure is demarcated into categories of emotion and color, renowned as elementary psychological phenomena. This is achieved by means of quantum-theoretic qubit state space, isomorphic to emotion and color experiences both in meaning and math. In particular, colors are mapped to the qubit states through geometric affinity between the HSL-RGB color solids and the Bloch sphere, widely used in physics. The resulting correspondence aligns with the recent model of subjective experience, producing a unified spherical map of emotions and colors. This structure is identified as a semantic atom of natural thinking-a unit of affectively-colored personal meaning, involved in elementary acts of a binary decision. The model contributes to finding a unified ontology of both inert and living Nature, bridging previously disconnected fields of research. In particular, it enables theory-based coordination of emotion, decision, and cybernetic sciences, needed to achieve new levels of practical impact.
