Quantum theory of probability and decisions

Suppose that a quantum system S has density operator ρ̂ at the instant when an observable X̂ of S is to be accurately measured. The outcome of the measurement must be one of the eigenvalues of X̂, but quantum theory does not in general specify which. Instead, in conventional formulations of the theory (see, for example, d’Espagnat 1976; Cohen-Tannoudji et al . 1978), a statement such as the follow...

Quantum Probability Theory

The mathematics of classical probability theory was subsumed into classical measure theory by Kolmogorov in 1933. Quantum theory as nonclassical probability theory was incorporated into the beginnings of noncommutative measure theory by von Neumann in the early thirties, as well. To precisely this end, von Neumann initiated the study of what are now called von Neumann algebras and, with Murray,...

Fuzzy Quantum Probability Theory

This paper surveys some of the recent results that have been obtained in fuzzy quantum probability theory. In this theory fuzzy events are represented by quantum effects and fuzzy random variables are represented by quantum measurements. Probabilities, conditional probabilities and sequential products of effects are discussed. The relationship between the law of total probability and compatibil...

Quantum Probability from Decision Theory?

In a recent paper, Deutsch [1] claims to derive the “probabilistic predictions of quantum theory” from the “non-probabilistic axioms of quantum theory” and the “non-probabilistic part of classical decision theory.” We show that his derivation fails because it includes hidden probabilistic assumptions.

Probability and entropy in quantum theory

Entropic arguments are shown to play a central role in the foundations of quantum theory. We prove that probabilities are given by the modulus squared of wave functions, and that the time evolution of states is linear
