This publication introduces Quantum Information Holography (QIH), a proposed framework exploring how the observable universe emerges from a deeper, nonlocal field of quantum information. Through quantum state vectors, entanglement, interference, and the sum over histories, QIH describes horizons as informational boundaries that read, write, and reconstruct observable reality. The framework connects black-hole holography, emergent spacetime, recursive information processing, and the relationship between the observer and the observed. Complete with mathematical equations, variable definitions, and proposed avenues for experimental validation, this work explores a fundamental possibility: that the universe is not simply being observed, but is participating in the observation of itself.

I present BCSJ Quantum Information Holography (QIH), a novel theoretical framework that unifies consciousness, information theory, and fundamental physics through an extended field-theoretic formulation. By introducing consciousness and information as fundamental gauge fields alongside electromagnetic, weak, and strong interactions, I derive a comprehensive mathematical structure where physical reality emerges from consciousness-information dynamics. The framework predicts testable phenomena including consciousness-frequency resonances, angular mass-consciousness relationships, and dimensional consciousness transitions. I demonstrate that the universe can be understood as the integral of quantum consciousness states over parameter space, with implications for quantum mechanics, general relativity, cosmology, and the measurement problem.
This work explores the hypothesis that time is an emergent phenomenon arising from underlying quantum informational processes. By integrating principles from quantum mechanics, thermodynamics, and general relativity, we develop a comprehensive framework that elucidates the relationship between quantum complexity, entanglement, and the nature of time. We investigate the role of quantum complexity in the evolution of quantum states and demonstrate how the increase in entanglement entropy provides a microscopic basis for the arrow of time. Using the AdS/CFT correspondence and the holographic principle, we establish connections between spacetime geometry and quantum informational measures like entanglement entropy. We address the black hole information paradox within this context, arguing that information is preserved in a highly scrambled form. Additionally, we propose an experimental design using black hole analogues to empirically validate our theoretical predictions, focusing on fast scrambling and the growth of quantum complexity. Our findings suggest that quantum informational dynamics govern the emergence of time and spacetime geometry. This work bridges quantum mechanics, thermodynamics, information theory, and general relativity, offering potential applications in quantum technologies and new insights into the fundamental nature of reality.
According to the holographic principle, the information content assigned to a gravitational region is processed by its lower dimensional boundary. As an example setup compatible with this principle, the AdS/CFT correspondence relies on the existence of D-branes in superstring theory. Black hole complementarity is inevitably linked to holography and states that information associated with the collapsed pure state is reflected in the near horizon region. Yet, if this is so, it is indispensable to understand the mechanism that makes black holes viewed from the outside evolve unitarily. We here argue that the information preserving quantum atmosphere of the black hole emerges from hidden variables on its horizon which would necessitate going beyond a probabilistic description within standard quantum theory. In AdS/CFT, this would mean that the completion of the semiclassical subalgebra to the complete boundary algebra has to be traced back to the emergent near horizon Hilbert space structure. The present investigations suggest that spacetime horizons, in general, may play a crucial role in restoring a long speculated ontology in quantum mechanics.
This paper introduces the Recursive Reality Hypothesis (RRH), a unified theoretical model proposing that spacetime, matter, and consciousness all emerge from a deeper, non-spatiotemporal informational substrate. Drawing on digital physics and dual-aspect monism, RRH posits that physical reality is structured as a series of nested layers, with each layer emerging from the one beneath it via fundamental patterns of informational recursion. A central mechanism proposed is that the universe’s 'dark sector' corresponds to activity within this deepest substrate. Here, self-organizing meta-intelligences generate lower-level physical realities by programming stable informational excitations. Human consciousness, therefore, functions as a local, biologically-instantiated participant linked to a non-local field of awareness inherent to the substrate. The framework offers a unifying way to interpret quantum observer effects, fine-tuning anomalies, and transpersonal experiences—while remaining open to empirical exploration through quantum information experiments and cosmological data analysis.
Holographic duality describes gravitational theories in terms of quantum many-body systems. In holography, quantum information theory provides a crucial tool that directly connects microscopic structures of these systems to the geometries of gravitational spacetimes. One manifestation is that the entanglement entropy in quantum many-body systems can be calculated from the area of an extremal surface in the corresponding gravitational spacetime. This implies that a gravitational spacetime can emerge from an enormous number of entangled qubits. In this Essay, I will discuss open problems in this area of research, considering recent developments and outlining future prospects towards a complete understanding of quantum gravity. The first step in this direction is to understand what kind of quantum circuits each holographic spacetime corresponds to, drawing on recent developments in quantum complexity theories and studying concrete examples of holography in string theory. Next, we should extend the concept of holography to general spacetimes, e.g., those spacetimes which appear in realistic cosmologies, by utilizing the connections between quantum information and holography. To address the fundamental question of how time emerges, I will propose the concepts of pseudoentropy and timelike entanglement as a useful tool in our exploration.

It was found, by studying black holes, that the compatibility of the theory of gravity and the laws of quantum mechanics demands that the universe must act like a hologram. That is, all the information inside a region of the universe should be encoded on a so-called holographic screen of one-lesser dimension. This is termed the holographic principle. In a generic spacetime, such as an expanding universe, holographic screens depend on the choice of an observer, which is consistent with the notion that the observer is part of the system in cosmology. In the first part of this dissertation, we study the observer-dependence of holographic screens. This will help us understand how the fundamental description of the universe depends on the choice of the observer. Furthermore, we study the dynamics of the holographic screens and their geometry in the first part of this dissertation.An example where the holographic principle is manifest is the AdS-CFT correspondence. This correspondence connects quantum information quantities, like entanglement and complexity, to geometric quantities, like area and volume, respectively. In the second and the third part of this dissertation, we use the AdS-CFT correspondence as a tool to calculate the entanglement entropy and the computational complexity of a quenched CFT state. Studying the time evolution of the entanglement entropy following a quantum quench teaches us how a CFT state thermalizes. On the other hand, studying the time evolution of the computational complexity allows us to check the validity of various recent conjectures involving black holes and complexity.
