Entangled states considered as physical representations of classical algorithms

TL;DR

This paper explores the philosophical implications of classical states and decoherence, proposing that classical behavior emerges from quantum-like entanglement and supports a multiverse perspective.

Contribution

It introduces a novel interpretation of classical states as entangled representations of algorithms, linking decoherence to the emergence of classicality and the multiverse concept.

Findings

Classical states can be viewed as entangled representations of algorithms.

Decoherence explains the emergence of classical behavior from quantum-like states.

Supports a multiverse interpretation of physical reality.

Abstract

There are good reasons to believe that we are classical algorithms run on (effectively) classical machines. However, the fact that a physical state of a system in a universe described by a classical deterministic model doesn't contain any information about the model's evolution laws, gives rise to deep philosophical paradoxes with this picture of what we are. We explain these paradoxes in detail and show that they can be resolved once we take into account that in the real world, classical behavior arises as a result of decoherence. We then show that this solution naturally leads to a variant of the idea of a mathematical multiverse, originally proposed by Tegmark.
