Time, quantum mechanics, and decoherence

  title={Time, quantum mechanics, and decoherence},
  author={Simon Saunders},
State-reduction and the notion of “actuality” are compared to “passage” through time and the notion of “the present”; already in classical relativity the latter give rise to difficulties. The solution proposed here is to treat both tense and value-definiteness as relational properties or “facts as relations”; likewise the notions of change and probability. In both cases “essential” characteristics are absent: temporal relations are tenselessly true; probabilistic relations are deterministically… 
Time, quantum mechanics, and tense
A comparative study of the sense in which physical theories can lend expression to the metaphysics at issue and to establish that the same issues are at stake in the relational approach to value-definiteness and probability in quantum mechanics.
Timeless Configuration Space and the Emergence of Classical Behavior
This paper attempts to give an alternative answer to the issues faced by consistent histories, by exploring a timeless interpretation of quantum mechanics of closed systems, done solely in terms of path integrals in non-relativistic, timeless, configuration space.
Everettian quantum mechanics without branching time
This paper assesses the prospects for combining contemporary Everettian quantum mechanics with branching-time semantics in the tradition of Kripke, Prior, Thomason and Belnap, and concludes by discussing and rejecting an alternative possible motivation for branching time.
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
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. One
Quantum Structures of a Model-Universe: An Inconsistency with Everett Interpretation of Quantum Mechanics
We observe a Quantum Brownian Motion (QBM) Model Universe in conjunction with recently established Entanglement Relativity and Parallel Occurrence of Decoherence. The Parallel Occurrence of
Fundamentality and Levels in Everettian Quantum Mechanics
Distinctions in fundamentality between different levels of description are central to the viability of contemporary decoherence-based Everettian quantum mechanics (EQM). This approach to quantum
Multiplicity in Everett's interpretation of quantum mechanics
Two Dogmas About Quantum Mechanics
We argue that the intractable part of the measurement problem -- the 'big' measurement problem -- is a pseudo-problem that depends for its legitimacy on the acceptance of two dogmas. The first dogma
Quantum physics and human language
Human languages employ constructions that tacitly assume specific properties of the limited range of phenomena they evolved to describe. These assumed properties are true features of that limited


Consistent histories and the interpretation of quantum mechanics
The usual formula for transition probabilities in nonrelativistic quantum mechanics is generalized to yield conditional probabilities for selected sequences of events at several different times,
Quantum temporal logic and decoherence functionals in the histories approach to generalized quantum theory
The recent suggestion that a temporal form of quantum logic provides the natural mathematical framework within which to discuss the proposal by Gell‐Mann and Hartle for a generalized form of quantum
Aspects of the Decoherent Histories Approach to Quantum Mechanics
I give an informal overview of the decoherent histories approach to quantum mechanics , due to Griffiths, to Omnès, and to Gell-Mann and Hartle is given. Results on the connections between
Consistent interpretations of quantum mechanics
Within the last decade, significant progress has been made towards a consistent and complete reformulation of the Copenhagen interpretation (an interpretation consisting in a formulation of the
"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
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, relative states, and evolutionary adaptation
We review the decoherent histories approach to the interpretation of quantum mechanics. The Everett relative-state theory is reformulated in terms of decoherent histories. A model of evolutionary
Quantum mechanics of history: The decoherence functional in quantum mechanics.
A condition for approximate decoherence is proposed, and it is argued that most probability sum rules will be satisfied to approximately the same degree, and an inequality bounding the size of the off-diagonal terms of thedecoherence functional is derived.
Classical equations for quantum systems.
This work investigates the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e., such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones.
