On Zurek’s Derivation of the Born Rule

  journal={Foundations of Physics},
Recently, W. H. Zurek presented a novel derivation of the Born rule based on a mechanism termed environment-assisted invariance, or “envariance” [W. H. Zurek, Phys. Rev. Lett. 90(2), 120404 (2003)]. We review this approach and identify fundamental assumptions that have implicitly entered into it, emphasizing issues that any such derivation is likely to face.

Quantum probabilities from combination of Zurekʼs envariance and Gleasonʼs theorem
The quantum-mechanical rule for probabilities, in its most general form of positive-operator valued measure, is shown to be a consequence of the environment-assisted invariance (envariance) idea
Zurek’s envariance derivation of Born’s rule and measurement
Zurek’s derivation of Born’s rule using envariance (invariance due to entanglement) is considered to capture the probability in full generality, but only as applied to the measurement of a quantum
Born Rule and Noncontextual Probability
We present a new derivation of the Born rule from the assumption of noncontextual probability (NCP). Within the theorem we also demonstrate the continuity of probability with respect to the
Born Rule and its Interpretation
The Born rule provides a link between the mathematical formalism of quantum theory and experiment, and as such is almost single-handedly responsible for practically all predictions of quantum
On the Explanation of Born-Rule Statistics in the de Broglie-Bohm Pilot-Wave Theory
It is suggested that there is somewhat less conflict between the two approaches than existing polemics might suggest, and that indeed elements from both arguments may be combined to provide a unified and fully-compelling explanation from the postulated dynamical first principles, of the Born rule.
Quantum probability law from ‘environment-assisted invariance’ in terms of pure-state twin unitaries
Zurek's derivation of the Born rule from envariance (environment-assisted invariance) is retraced in an attempt to present a more detailed derivation, which is extended to encompass the trace-rule
Many-particle interference to test Born's rule
Born's rule, one of the cornerstones of quantum mechanics, relates detection probabilities to the modulus square of the wave function. Single-particle interference is accordingly limited to pairs of
Towards a theory of wavefunction collapse Part 1: How the Diosi-Penrose criterion and Born's rule can be derived from semiclassical gravity, and how the criterion can be relativistically generalised with help of the Einstein-Hilbert action
A new approach to wavefunction collapse is prepared by an analysis of semiclassical gravity. The fact that, in semiclassical gravity, superposed states must share a common classical spacetime

The Born rule is derived from operational assumptions, together with assumptions of quantum mechanics that concern only the deterministic development of the state, and provides a probability rule for state spaces that are not Hilbert spaces.
Zurek claims to have derived Born's rule noncircularly in the context of an ontological no-collapse interpretation of quantum states, without any "deus ex machina imposition of the symptoms of
No-signalling-based version of Zurek's derivation of quantum probabilities: A note on "Environment-assisted invariance, entanglement, and probabilities in quantum physics"
Zurek has derived the quantum probabilities for Schmidt basis states of bipartite quantum systems in pure joint states, from the assumption that they should be not be affected by one party's action
The Everett Interpretation
We begin with an essentially technical notion that will be used repeatedly in what follows. Indeed, it will serve as our conduit between physical observations and the mathematical formalism of
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

Decoherence, the measurement problem, and interpretations of quantum mechanics
Environment-induced decoherence and superselection have been a subject of intensive research over the past two decades, yet their implications for the foundational problems of quantum mechanics, most
This is a critical review of the literature on many-worlds interpretations, MWI, with arguments drawn partly from earlier critiques by Bell and Stein. The essential postulates involved in various MWI
