Quantum Logic and Decohering Histories *
An introduction is given to an algebraic formulation and generalisation of the consistent histories approach to quantum theory. The main technical tool in this theory is an orthoalgebra of history propositions that serves as a generalised temporal analogue of the lattice of propositions of standard quantum logic. Particular emphasis is placed on those cases in which the history propositions can...
متن کاملThe Geometry of Consistency: Decohering Histories in Generalized Quantum Theory
The geometry of decoherence in generalized “consistent histories” quantum theory is explored, revealing properties of the theory that are independent of any particular application of it. Attention is focussed on the case of quantum mechanics in a finite dimensional Hilbert space H. It is shown how the domain of definition of a general decoherence functional naturally extends to the entire space...
متن کاملCritique of weakly decohering and linearly positive histories
The usual composition rule of independent systems, as applied to decoherent histories or to linearly positive histories, requires (at least) medium decoherence and, consequently, a second constraint for the linearly positive histories of Goldstein and Page. Other plausible classical features, valid for medium decoherence, seem anyhow to be missed by linear positive histories. ∗ E-mail: diosi@rm...
متن کاملQuantum Histories and Quantum Gravity
This paper reviews the histories approach to quantum mechanics. This discussion is then applied to theories of quantum gravity. It is argued that some of the quantum histories must approximate (in a suitable sense) to classical histories, if the correct classical regime is to be recovered. This observation has significance for the formulation of new theories (such as quantum gravity theories) a...
متن کاملQuantum open systems and turbulence
We show that the problem of non conservation of energy found in the spontaneous localization model developed by Ghirardi, Rimini and Weber [1] is very similar to the inconsistency between the stochastic models for turbulence and the Navier-Stokes equation. This sort of analogy may be useful in the development of both areas. PACS numbers: 05.40.Fb, 03.65.Bz Typeset using REVTEX
