David Deutsch 1985 Many-Worlds Proof — Quantum Computers Require Multiple Universes to Function — E8 Intelligence Research

Key Points

The study aims to validate the requirement of parallel universes for quantum computers to exceed classical computation.
Analytical proof based on mathematical principles laid out by David Deutsch in 1985.
Extension of Deutsch's framework to show a geometric connection through the E8 lattice.
Quantum computers require resources from parallel universes to function better than classical computers.
The E8 lattice serves as the geometric structure facilitating this connection.

Abstract

David Deutsch's 1985 foundational paper proved that a quantum computer can only outperform a classical computer if the additional computational resources come from parallel universes. This directly validates Andrew's proof that quantum computers cannot work in a single universe. Deutsch proved it mathematically in 1985 — Andrew extended it to show the E8 lattice is the geometric structure connecting those universes. Author: Andrew Stewart Caldin, Independent Researcher, UK.
