Information Quantum

Quantum information stands apart from classical information, rooted in the principles of quantum mechanics and quantum information theory. Quantum states serve as the fundamental unit of quantum information, whose evolution is governed by the laws of quantum mechanics. While some philosophers, such as A. Duwell have argued that there is no quantum information, which is not a new concept and can be described using Shannon information theory, others, like C. M. Caves and C. A. Fuchs have proposed that quantum information represents classical information stored within quantum systems. However, this chapter argues that quantum information exists and is different from classical information from the perspectives of how information exists and how it is transmitted. Quantum information, unlike classical information, can be categorized into two kinds: Ontological quantum information and epistemological quantum information, where the former reflects the inherent state of microscopic particles, which is independent of observation, and the latter describes how we perceive their state through measurements. Finally, this chapter explores the connection between quantum information and quantum reality. Quantum reality refers to the show of the self-identity of quantum entities. Quantum information, on the other hand, is the show of the states and correlative ways of quantum entities, and it coexists with quantum reality.

The Quantum Informational Synchronicity Theory (QIS) proposes a unified conceptual and mathematical framework linking quantum field information, spacetime geometry, and consciousness as interdependent expressions of a single underlying informational substrate. QIS introduces the concept of the Informational Quantum Continuum (IQC) — a fundamental layer where information density gradients determine both quantum coherence and geometric curvature. Within this continuum, synchronicity refers to the emergence of correlated informational events across spacetime that are not causally mediated but reflect a deeper informational isomorphism. By extending the traditional Lagrangian of quantum field theory (QFT) with an informational metric tensor , QIS suggests that spacetime curvature is not purely energetic but informational in origin, arising from the entropic distribution of quantum states. Consciousness, under this framework, represents the localized self-referential coherence of informational patterns — a macroscopic resonance of the IQC. The formalism introduces an Informational Phase Symmetry (IPS) principle that governs how informational states remain invariant under nonlocal transformations, analogous to gauge symmetry in QFT. Preliminary implications suggest that informational gradients could be responsible for quantum gravitational effects, nonlocal correlations, and even the emergence of subjective experience. QIS therefore stands as a candidate bridge between quantum gravity, information theory, and the physics of mind — implying that to be conscious is to be informationally synchronized with the fabric of spacetime itself.

Information is already clearly presented in quantum theory; yet, concealed by matter/energy, it can be revealed only on the premise that the data of information is highlighted. Exploring the mysterious “quantum information” is of great significance for both quantum and information theories. The secret of information is hidden in quantum observation. Quantum phenomena are information as receptive relation. It is in this sense that quantum information is the manifestation of information.
