Many Worlds, the Cluster-state Quantum Computer, and the Problem of the Preferred Basis

TL;DR

The paper critiques the many worlds explanation of quantum computation, arguing it is incompatible with the cluster state model and suggesting it should be rejected as a conceptual framework.

Contribution

It provides a critical analysis showing the incompatibility of the many worlds interpretation with the cluster state quantum computing model.

Findings

Many worlds explanation is incompatible with cluster state quantum computation

The many worlds interpretation is conceptually inferior for explaining quantum computation

The paper advocates rejecting the many worlds explanation in this context

Abstract

I argue that the many worlds explanation of quantum computation is not licensed by, and in fact is conceptually inferior to, the many worlds interpretation of quantum mechanics from which it is derived. I argue that the many worlds explanation of quantum computation is incompatible with the recently developed cluster state model of quantum computation. Based on these considerations I conclude that we should reject the many worlds explanation of quantum computation.
