The measurement postulates of quantum mechanics are operationally redundant

L Masanes, TD Galley, MP Müller - Nature communications, 2019 - nature.com
Understanding the core content of quantum mechanics requires us to disentangle the
hidden logical relationships between the postulates of this theory. Here we show that the …

Ideas abandoned en route to QBism

BC Stacey - arxiv preprint arxiv:1911.07386, 2019 - arxiv.org
The interpretation of quantum mechanics known as QBism developed out of efforts to
understand the probabilities arising in quantum physics as Bayesian in character. But this …

An alternative foundation of quantum theory

IS Helland - Foundations of Physics, 2024 - Springer
A new approach to quantum theory is proposed in this paper. The basis is taken to be
theoretical variables, variables that may be accessible or inaccessible, ie, it may be possible …

Contextuality in composite systems: the role of entanglement in the Kochen-Specker theorem

VJ Wright, R Kunjwal - Quantum, 2023 - quantum-journal.org
Abstract The Kochen–Specker (KS) theorem reveals the nonclassicality of single quantum
systems. In contrast, Bell's theorem and entanglement concern the nonclassicality of …

Everettian probabilities, the Deutsch-Wallace theorem and the Principal Principle

HR Brown, GB Porath - Quantum, probability, logic: the work and influence …, 2020 - Springer
This paper is concerned with the nature of probability in physics, and in quantum mechanics
in particular. It starts with a brief discussion of the evolution of Itamar Pitowsky's thinking …

[PDF][PDF] A new approach toward the quantum foundation and some consequences

IS Helland - Academia Quantum, 2024 - academia.edu
A general theory based on six postulates is introduced. The basic notions are theoretical
variables that are associated with an observer or with a group of communicating observers …

General probabilistic theories with a Gleason-type theorem

VJ Wright, S Weigert - Quantum, 2021 - quantum-journal.org
Gleason-type theorems for quantum theory allow one to recover the quantum state space by
assuming that (i) states consistently assign probabilities to measurement outcomes and that …

Toward a World Game-Flavored as a Hawk's Wing

BC Stacey - Phenomenology and QBism, 2023 - taylorfrancis.com
The interpretation of quantum mechanics known as QBism developed out of efforts to
understand the probabilities arising in quantum physics as Bayesian in character. But this …

Are Non-Boolean Event Structures the Precedence or Consequence of Quantum Probability?

CA Fuchs, BC Stacey - Probing the Meaning of Quantum Mechanics …, 2024 - World Scientific
In the last five years of his life Itamar Pitowsky developed the idea that the formal structure of
quantum theory should be thought of as a Bayesian probability theory adapted to the …

Gleason-type theorems from Cauchy's functional equation

VJ Wright, S Weigert - Foundations of Physics, 2019 - Springer
Gleason-type theorems derive the density operator and the Born rule formalism of quantum
theory from the measurement postulate, by considering additive functions which assign …
