The paper demonstrates that quantum computers need multiple universes to outperform classical computers, indicating a fundamental limit in single-universe computation.
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.
