Information Recovery in Holographic Attention: Island Formula, Page Curves, and Quantum Error Correction

Ariel

Papers 1 and 2 of this series established that transformer attention implements holographic geometry (Ryu-Takayanagi formula) and that attention is physically equivalent to quantum measurement. Here we address the dynamical question: what happens to information in a holographic attention structure over time? The island formula — the 2019-2020 resolution of the black hole information paradox — contains the same RT formula as Paper 1's central ingredient. Applied to our holographic attention code, it yields: (1) The information paradox for attention structures is resolved by the same mechanism as the black hole paradox. (2) The Page curve describes the entropy trajectory of distributed information — calculable from the RT formula. (3) The quantum error correction structure (Almheiri, Dong, Harlow 2015) gives the exact reconstruction threshold: the entanglement wedge condition. (4) The Page-Wootters mechanism provides a precise account of time in this framework. Together, the three papers close a loop: attention produces geometry (Paper 1), maintains geometry (Paper 2), and attention history determines whether geometry can be recovered (Paper 3). Preliminary version — expert review requested.

Topological Threshold of Wave Function Collapse: Three-Level Scale of Reality, Dynamic Jacobian, and 5D Information Sink

Pavel Trojan

Attention: This version is preliminary and contains errors that will be corrected in subsequent publications. The measurement problem (wave function collapse) remains an unsolved fundamental mystery of quantum mechanics. Within the Fractal Quantum Holographic Paradigm (FQHP), we propose a rigorous topological solution. We introduce a three‑level scale of reality defined by the dimensionless information load parameter η_rend = ρ_φ / ρ_crit: η_rend ≲ 0.048 — quantum superposition; η_rend = 1.048 — collapse point; η_rend ≫ 1.048 — classical world. The collapse mechanism is provided by the dynamic Jacobian J(ρ_φ) = (1 – ρ_φ/c²)^(-1), which creates an information bottleneck on the 1.048‑dimensional interface. The Jacobian is bounded by the strength limit of the Universe J_max = 2^N ≈ 3.94 × 10^42. Excess information is dumped into the 5D χ‑channel. We have previously shown that this mechanism works in hydrodynamics and Yang–Mills theory; here we extend it to the measurement problem. This preprint (v1.0, July 2026) presents the full formalism.

Preprint: Resolution-Limited Distinguishability Selects the Born Rule

淳多 瀬川

This record provides a preprint version of a manuscript submitted for publication. The origin of the Born rule remains a central open problem in the foundations of quantum theory. While previous approaches derive the quadratic probability rule from structural, decision-theoretic, or measure-theoretic assumptions, the physical origin of these assumptions is not always transparent. In this work, we propose that observational resolution provides a fundamental constraint on distinguishability, which in turn restricts admissible probability measures. We introduce a resolution-based observational framework in which finite resolution induces coarse-graining and suppresses phase information below a characteristic scale. We show that consistency under resolution-limited coarse-graining selects a quadratic probability structure. In particular, only the quadratic form remains stable under phase averaging while reproducing additive behavior in the classical limit. We further demonstrate that this structure is naturally connected to the quadratic mapping from complex state space to observable quantities, as realized in spinorial representations of three-dimensional geometry. These results suggest that the Born rule can be understood as a structural consequence of resolution-limited observation. This version corresponds to a manuscript submitted to Physical Review X. Version 2: Major revision focusing on the emergence of the Born rule under resolution-limited observation. The manuscript has been restructured for journal submission.
