We sketch a quantum mechanical framework for the universe as a whole. Within that framework we propose a program for describing the ultimate origin in quantum cosmology of the quasiclassical domain of familiar experience and for characterizing the process of measurement. Predictions in quantum mechanics are made from probabilities for sets of alternative histories. Probabilities can be assigned only to sets of histories that approximately decohere. Decoherence is defined and the mechanism of… Expand

Quantum equilibrium and the origin of absolute uncertainty
The quantum formalism is a “measurement” formalism-a phenomenological formalism describing certain macroscopic regularities. We argue that it can be regarded, and best be understood, as arising fromExpand
The consistent histories approach to loop quantum cosmology
We review the application of the consistent (or decoherent) histories formulation of quantum theory to canonical loop quantum cosmology. Conventional quantum theory relies crucially on "measurements"Expand
Quantum Cosmology and the Emergence of a Classical World
Quantum cosmology is the application of quantum theory to the Universe as a whole. At first glance such an attempt seems surprising since one is used to apply quantum theory to microscopic systems.Expand
On the Consistency of the Consistent Histories Approach to Quantum Mechanics
TLDR
The present work questions the validity of claims offered by CH proponents asserting that it solves many interpretational problems in quantum mechanics, and critically examines the proposed notion of a realm-dependent reality. Expand
Consistent probabilities in loop quantum cosmology
A fundamental issue for any quantum cosmological theory is to specify how probabilities can be assigned to various quantum events or sequences of events such as the occurrence of singularities orExpand
A Review of the Decoherent Histories Approach to Quantum Mechanics a
I review the decoherent (or consistent) histories approach to quantum mechanics, due to Griffiths, to Gell-Mann and Hartle, and to Omnes. This is an approach to standard quantum theory specificallyExpand
Probabilities and Quantum Reality: Are There Correlata?
Any attempt to introduce probabilities into quantum mechanics faces difficulties due to the mathematical structure of Hilbert space, as reflected in Birkhoff and von Neumann's proposal for a quantumExpand
