We explore definite theoretical assertions about consciousness, starting from a non-reductive psycho-informational solution of David Chalmers's 'hard problem', based on the hypothesis that a fundamental property of 'information' is its experience by the supporting 'system'. The kind of information involved in consciousness needs to be quantum for multiple reasons, including its intrinsic privacy and its power of building up thoughts by entangling qualia states. As a result we reach a quantum-information-based panpsychism, with classical physics supervening on quantum physics, quantum physics supervening on quantum information, and quantum information supervening on consciousness. We then argue that the internally experienced quantum state, since it corresponds to a definite experience-not to a random choice-must be pure, and we call it ontic, in contrast with the state predictable from the outside (i.e. the state describing the knowledge of the experience from the point of view of an external observer) which we call epistemic and is generally mixed. Purity of the ontic state requires an evolution that is purity preserving, namely a so-called 'atomic' quantum operation. The latter is generally probabilistic, and its particular outcome is interpreted as the free will, which is unpredictable even in principle since quantum probability cannot be interpreted as lack of knowledge. The same purity of state and evolution allows solving the 'combination problem' of panpsychism. Quantum state evolution accounts for a short-term buffer of experience and contains itself quantum-to-classical and classical-to-quantum information transfers. Long term memory, on the other hand, is classical, and needs memorization and recall processes that are quantum-to-classical and classical-to-quantum, respectively...

Quantum entanglement, a cornerstone of quantum mechanics, presents a profound challenge to classical intuition. This paper explores the potential of extending this peculiar phenomenon to encompass non-local correlations, proposing a novel framework termed "Entanglement Non-Locality" (ENL). The core claim is to establish a theoretical foundation for this non-locality, leveraging the inherent properties of entangled states to simulate quantum information transfer and associate it with classical information transfer. We hypothesize that by embedding entanglement within a non-local field theory, we can achieve enhanced quantum information processing and communication capabilities. This research delves into the design of such a field theory, examining its potential to overcome limitations imposed by classical physics and unlock new avenues for quantum technologies.

Quantum mechanics discovers fascinating concepts like entanglement, in which subatomic particles stay correlated regardless of distance. Measurements on one particle instantaneously influence the other, defying classical expectations. While the principles of quantum mechanics suggest the possibility of faster-than-light information transfer, experiments such as quantum teleportation and entanglement exchange indicate this more explicitly. However, it’s crucial to distinguish this from the speed limit of light established by special relativity. This chapter argues that the superluminal aspect observed in these processes pertains to ontological information, and not the actual physical movement of micro-particles; in contrast, epistemological information, derived from measurements, remains bound by the speed of light. Microscopic particles possess both intrinsic properties (their own nature) and extrinsic properties (how they interact with the environment). This duality extends to their identity and distinguishability. Quantum teleportation experiments demonstrate that quantum reality unites quantum information within these micro-particles; in addition, quantum information can be transferred through specific quantum processes.
