Consistent Sets Yield Contrary Inferences in Quantum Theory
In the consistent histories formulation of quantum theory, the probabilistic predictions and retrodictions made from observed data depend on the choice of a consistent set. We show that this freedom allows the formalism to retrodict contrary propositions which correspond to orthogonal commuting projections and which each have probability one. We also show that the formalism makes contrary proba...
متن کاملConsistent Histories and Contrary Inferences
Consistent History Approach to quantum theory, introduced in explicit form by Griffiths [1], provides an extension of the interpretation of the formalism of quantum mechanics. While standard quantum theory is based on the concept of event, represented by a projection operator E of the Hilbert spaceH describing the system, CHA is based on the concept of history, which is a finite ordered sequenc...
متن کاملConsistent Sets and Contrary Inferences: Reply to Griffiths and Hartle
It was pointed out recently [A. Kent, Phys. Rev. Lett. 78 (1997) 2874] that the consistent histories approach allows contrary inferences to be made from the same data, corresponding to commuting orthogonal projections in different consistent sets. To many, this seems undesirable in a theory of physical inferences. It also raises a specific problem for the consistent histories formalism, since t...
متن کاملReview of Consistent Quantum Theory
The book under review is devoted to a proposal for resolving the problem of the foundations of quantum mechanics. There are two parts: first the essentials of quantum theory, and then a variety of applications with emphasis on the paradoxical features of the theory and on measurement situations. The level of the book is comparable to that of other introductions to quantum theory, but it concent...
متن کاملComment on “ Consistency , amplitudes , and probabilities in quantum theory ”
In a recent article [Phys. Rev. A 57, 1572 (1998)] Caticha has concluded that " nonlinear variants of quantum mechanics are inconsistent. " In this note we identify what it is that nonlinear quantum theories have been shown to be inconsistent with.
