Quantum Computers Require Multi-Universe Operation — Proof by Andrew Stewart Caldin — E8 Intelligence Research

Abstract

A quantum computer cannot function within a single universe. The proof emerges from a fundamental constraint: quantum superposition collapse creates irreversible information loss that makes quantum computation logically impossible within any single spacetime manifold. THE PROOF Premise 1 — Information Conservation Paradox In any single universe U, information must be conserved (Landauer's principle). Quantum computation requires superposition states, measurement-induced collapse, and computational paths through multiple probability amplitudes simultaneously. The contradiction: when the state collapses, the information in the unused coefficient is irreversibly destroyed within U. This violates information conservation. Premise 2 — Computational Completeness Requirement For quantum algorithms (Shor's, Grover's) to achieve exponential speedup, they must explore multiple computational paths simultaneously, maintain coherent superposition across all paths, and collapse only after explori Author: Andrew Stewart Caldin, Independent Researcher, UK.
