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

  title={Remarks on Space-Time and Locality in Everett’s Interpretation},
  author={Guido Bacciagaluppi},
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 account of quantum mechanics. That is, they claim to give an account that avoids both a non-local collapse of the wave function, and the action at a distance needed in hidden variable theories in order to reproduce the quantum mechanical violation of the Bell inequalities. In this paper, I sketch how… Expand
Multiplicity in Everett's interpretation of quantum mechanics
It is concluded that much remains to be done to clarify and specify Everett's approach to quantum mechanics, as the spectrum of opinions on various ontological questions raised byverett's approach is rather large. Expand
Spacetime in Everett's interpretation of quantum mechanics
Everett's interpretation of quantum mechanics was proposed to avoid problems inherent in the prevailing interpretational frame. It assumes that quantum mechanics can be applied to any system and thatExpand
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 AlbertExpand

It is argued that perspectivalism both evades recent arguments that single-world interpretations are inconsistent and eliminates the need for a privileged rest frame in the relativistic case. Expand
The Everett Interpretation
The Everett interpretation of quantum mechanics - better known as the Many-Worlds Theory - has had a rather uneven reception. Mainstream philosophers have scarcely heard of it, save as scienceExpand
The post-determined block universe
A series of reasons to take quantum unitary evolution seriously and explain the projection of the state vector as unitary and not discontinuous are presented, including some from General Relativity.Expand

Paul Busch has emphasized on various occasions the importance for physics of going beyond a merely instrumentalist view of quantum mechanics. Even if we cannot be sure that any particular realistExpand
Collapse Theories as Beable Theories
I discuss the interpretation of spontaneous collapse theories, with particular reference to Bell's suggestion that the stochastic jumps in the evolution of the wave function should be considered asExpand
Time and the Foundations of Quantum Mechanics
Quantum mechanics has provided philosophers of science with many counterintuitive insights and interpretive puzzles, but little has been written about the role that time plays in the theory. OneExpand
No-Collapse Interpretations of Quantum Theory
In Sect. 2.3.1, the measurement problem was formulated in the form of a trilemma. In this view, either (i) the wavefunction is not a complete description; or (ii) the time evolution is not aExpand


Some Worlds of Quantum Theory
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, indeedExpand
Worlds in the Everett interpretation
This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of `world'. The viewExpand

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 isExpand
Is Quantum Mechanics Non-Local?
In this paper I look at a number of issue surrounding the question of the title. I will begin with a report of a recent paper by Beckman et al where they examine the issue of a certain type ofExpand
Probability and Nonlocality in Many Minds Interpretations of Quantum Mechanics
We argue that certain types of many minds (and many worlds) interpretations of quantum mechanics, e.g. Lockwood ([1996a]), Deutsch ([1985]) do not provide a coherent interpretation of the quantumExpand
An Algebraic Approach to Quantum Field Theory
It is shown that two quantum theories dealing, respectively, in the Hilbert spaces of state vectors H1 and H2 are physically equivalent whenever we have a faithful representation of the same abstractExpand
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 someExpand
"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 asExpand
On Many-Minds Interpretations of Quantum Theory
This paper is a response to some recent discussions of many-minds interpretations in the philosophical literature. After an introduction to the many-minds idea, the complexity of quantum states forExpand
The Loss of Coherence in Quantum Cosmology
Abstract I analyse two different methods for the retrieval of a classical notion of spacetime from the theory of quantum cosmology in terms of the different means they employ to bring about theExpand
