Some Worlds of Quantum Theory

  title={Some Worlds of Quantum Theory},
  author={Jeremy Butterfield},
  journal={arXiv: Quantum Physics},
Abstract: This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptual, indeed metaphysical, aspects rather than technical ones; but I include an introductory exposition of decoherence. In particular, I discuss whether---as these authors maintain---it is acceptable to have no precise definition of 'branch' (in the Everettian kind of sense). (A version of this paper will… 

Multiplicity in Everett's interpretation of quantum mechanics

On Time in Quantum Physics

First, I briefly review the different conceptions of time held by three rival interpretations of quantum theory: the collapse of the wave-packet, the pilot-wave interpretation, and the Everett

Nonlocality in Everettian Accounts of Quantum Mechanics

In this work we investigate the problem of locality in theories inspired by Everett’s Relative State Theory. Specifically we address the Many Worlds by Deutsch, the Many Minds Theory by David Albert

Remarks on Space-Time and Locality in Everett’s Interpretation

Interpretations that follow Everett's idea that (at some level of description) the universal wave function contains a multiplicity of coexisting realities, usually claim to give a completely local

The origin of the Everettian heresy $

In 1956, Hugh Everett, then a PhD student at Princeton, proposed his ‘‘relative state’’ formulation of quantum mechanics. John Wheeler, who was Everett’s advisor, recognized the originality and

A Top-down View of the Classical Limit of Quantum Mechanics

Since its birth in the early twentieth century, quantum mechanics raised a number of questions and problems, many of which are still a source of lively debate. The attempts to address those issues

Between classical and quantum

The Everett Interpretation of Quantum Mechanics: Many Worlds or None?

The doctoral dissertation of Hugh Everett, III-written under the direction of J. A. Wheeler-was principally motivated by the wish to obtain a reasonable basis for the quantization of general

"Relative State" Formulation of Quantum Mechanics

The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure as

Quantum Curiosities of Psychophysics

I survey some of these connections between 'collapse solutions' to the measurement problem, and the metaphysical doctrine of physicalism. I have two main conclusions. (1) These solutions, though

Identity and Probability in Everett's Multiverse

There are currently several versions of Everett's relative state interpretation of quantum mechanics, responding to a number of perceived problems for the original proposal. One of those problems is

On the consistent histories approach to quantum mechanics

We review the consistent histories formulations of quantum mechanics developed by Griffiths, Omnès, and Gell-Mann and Hartle, and describe the classification of consistent sets. We illustrate some

'Many Minds' Interpretations of Quantum Mechanics

Seventy years after the discovery of modern quantum mechanics, there is still no consensus as to how the theory should be understood. The philosophies of Niels Bohr and of the logical positivists,

Book Reviews: Quantum Mechanics. Historical Contingency and the Copenhagen Hegemony.

Why does one theory "succeed" while another, possibly clearer interpretation, fails? By exploring two observationally equivalent, yet conceptually incompatible, views of quantum mechanics, James T.

Book-Review - the Undivided Universe - an Ontological Interpretation of Quantum Theory

In the The Undivided Universe, David Bohn and Basil Hiley present a radically different approach to quantum theory. They develop an interpretation of quantum mechanics which gives a clear, intuitive

On schizophrenic experiences of the neutron or why we should believe in the many‐worlds interpretation of quantum theory

Abstract This is a philosophical paper in favor of the many‐worlds interpretation (MWI) of quantum theory. The necessity of introducing many worlds is explained by analyzing a neutron interference
