The Everett Interpretation

  title={The Everett Interpretation},
  author={D. Wallace},
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 science fiction. In philosophy of physics it is well known but has historically been fairly widely rejected. Among physicists (at least, among those concerned with the interpretation of quantum mechanics in the first place), it is taken very seriously indeed, arguably tied for first place in popularity with more… 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
On the Received Realist View of Quantum Mechanics
In this article I defend that an underlying framework exists among those interpretations of quantum mechanics which crucially consider the measurement problem as a central obstacle. I characteriseExpand
The problem of confirmation in the Everett interpretation
It is shown that in an Everettian context, the experimental evidence that is available could not provide empirical confirmation for quantum mechanics, and moreover that the authors would not even be able to establish reference to the theoretical entities of quantum mechanics. Expand
Realism and Intertheory Relationships: Interstructuralism, Closed Theories and the Quantum-Classical Limit
Today there is no agreement on which, if any, of the several known realist interpretations of quantum mechanics is the correct one, and disagreement on this matter is not merely verbal, butExpand
To Be a Realist about Quantum Theory
I look at the distinction between between realist and antirealist views of the quantum state. I argue that this binary classification should be reconceived as a continuum of different views aboutExpand

It is demonstrated that the Born rule is the uniquely rational way of apportioning credence in Everettian quantum mechanics, based on a single key principle: changes to the environment alone do not affect the probabilities one ought to assign to measurement outcomes in a local subsystem. Expand
Emergence of outcomes in quantum mechanics
A persistent focus on the concept of emergence as a core element of the scientific method allows a clean separation, insofar as this is possible, of the physical and philosophical aspects of theExpand
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

In a previous paper, Hayden and I (Deutsch & Hayden 2000 Proc. R. Soc. Lond. A 456, 1759–1774. (doi:10.1098/rspa.2000.0585)) proved, using the Heisenberg picture, that quantum physics satisfiesExpand
Quantum theory of the classical: quantum jumps, Born’s Rule and objective classical reality via quantum Darwinism

  • 2018
Three insights into the transition from quantum to classical that are based on the recognition of the role of the environment are described, including the derivation of preferred sets of states that help to define what exists—the authors' everyday classical reality. Expand


The Interpretation of Quantum Mechanics: Many Worlds or Many Words?
As cutting-edge experiments display ever more extreme forms of non-classical behavior, the prevailing view on the interpretation of quantum mechanics appears to be gradually changing. A (highlyExpand
The Interpretation of Quantum Mechanics
The interpretation of quantum mechanics has been controversial since the introduction of quantum theory in the 1920s. Although the Copenhagen interpretation is commonly accepted, its usualExpand
'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,Expand
Everett and structure
I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no definite values. TheExpand
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 localExpand
The Many-worlds interpretation of quantum mechanics
This volume contains Dr. Everett's short paper from 1957, "'Relative State' Formulation of Quantum Mechanics," and a far longer exposition of his interpretation, entitled "The Theory of the Universal Wave Function," never before published. Expand
The Einstein-Podolsky-Rosen correlations are very like many ordinary occurrences of everyday life. So it is a little difficult for the man in the street to understand immediately why there has beenExpand
One world versus many: the inadequacy of Everettian accounts of evolution, probability, and scientific confirmation
There is a compelling intellectual case for exploring whether purely unitary quantum theory defines a sensible and scientifically adequate theory, as Everett originally proposed. Many different andExpand
Comment on Lockwood
At the philosophical foundations of our best and deepest theory of the structure of reality, namely quantum mechanics, there is an intellectual scandal that reflects badly on most of this century'sExpand
Time, Quantum Mechanics, and Probability
It is shown that the relational theory needs nothing more than the physical, minimal criterion of identity as defined by Everett's theory, and that this can be transparently interpreted in terms of the ordinary notion of the chance occurrence of an event, as witnessed in the present. Expand
