# Time, quantum mechanics, and decoherence

@article{Saunders2005TimeQM, title={Time, quantum mechanics, and decoherence}, author={Simon Saunders}, journal={Synthese}, year={2005}, volume={102}, pages={235-266} }

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

- PhilosophySynthese
- 2004

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

- Physics
- 2015

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

- PhilosophySynthese
- 2011

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.

Fundamentality and Levels in Everettian Quantum Mechanics

- Philosophy

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…

Two Dogmas About Quantum Mechanics

- Philosophy
- 2007

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…

Quantum mechanics of history: The decoherence functional in quantum mechanics.

- PhysicsPhysical review. D, Particles and fields

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.

- PhysicsPhysical review. D, Particles and fields

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.
