Quantum Bayesianism, or QBism, is a recent development of the epistemic view of quantum states, according to which the state vector represents knowledge about a quantum system, rather than the true state of the system. QBism explicitly adopts the subjective view of probability, wherein probability assignments express an agent’s personal degrees of belief about an event. QBists claim that most if not all conceptual problems of quantum mechanics vanish if we simply take a proper epistemic and… 
Is QBism a Possible Solution to the Conceptual Problems of Quantum Mechanics
This work will examine if QBism's claims are robust and will show that a certain number of issues needs to be clarified in order to get a coherent picture.
On Quantum Bayesianism
The lately developed part of Quantum Bayesianism named QBism has been proclaimed by its authors a powerful interpretation of Quantum Physics. This article presents analysis of some aspects of QBism.
How Bayesian Probability Might Help Provide a Realist Interpretation of the Quantum Formalism
We offer a realist interpretation of non-relativistic quantum mechanics in which dynamical properties are properly possessed by the system in question, and are supposed to have definite values at any
Is Quantum Mechanics Self-Interpreting?
Fuchs and Peres (2000) claimed that standard Quantum Mechanics needs no interpretation. In this essay, I show the flaws of the arguments presented in support to this thesis. Specifically, it will be

The aim is to adopt the subjective probability interpretation of quantum mechanics, quantum Bayesianism (QBism), to serve quantum-like modelling and applications of quantum probability outside of physics.
QBism, FAPP and the Quantum Omelette. (Or, Unscrambling Ontological Problems from Epistemological Solutions in QM)
In this paper we discuss the so called "quantum omelette" created by Bohr and Heisenberg through the mix of (ontic) objective accounts and (epistemic) subjective ones within the analysis of Quantum

A simple probabilistic model is constructed allowing the existence of strong correlations between outcomes of distant measurements to be explained in a locally causal way and why the introduction of setting-dependent parameters does not restrict experimenters' freedom of choice.
EPR Paradox, Quantum Nonlocality and Physical Reality
Eighty years ago Einstein, Podolsky and Rosen demonstrated that instantaneous reduction of wave function, believed to describe completely a pair of entangled physical systems, led to EPR paradox. The
Reflections on Zeilinger–Brukner Information Interpretation of Quantum Mechanics
This note may be useful for general public interested in quantum foundations, especially because it tries to analyze essentials of the information interpretation critically (i.e., not just emphasizing its advantages as it is commonly done).


QBism, the Perimeter of Quantum Bayesianism
This article summarizes the Quantum Bayesian point of view of quantum mechanics, with special emphasis on the view's outer edges---dubbed QBism. QBism has its roots in personalist Bayesian
Quantum Mechanics Needs Interpretation
Since the beginning, quantum mechanics has raised major foundational and interpretative problems. Foundational research has been an important factor in the development of quantum cryptography,
Why Should We Interpret Quantum Mechanics?
The development of quantum information theory has renewed interest in the idea that the state vector does not represent the state of a quantum system, but rather the knowledge or information that we
Genuine Fortuitousness. Where Did That Click Come From?
The paper presents a revised view of quantum mechanics centered on the notion (“genuine fortuitousness”) that the click in a counter is a totally lawless event, which comes by itself. A crucial point
The whole is greater than the sum of the parts: on the possibility of purely statistical interpretations of quantum theory
It is shown that PBR's assumption of independence encodes an assumption of local causality, which is already known to conflict with the predictions of quantum theory via Bell-type inequalities.
The Transactional Interpretation of Quantum Mechanics
This book shows how TI can be used to solve the measurement problem of quantum mechanics and explain other puzzles, such as the origin of the 'Born Rule' for the probabilities of measurement results.
QBism: A Critical Appraisal
QBism is a novel interpretation of quantum mechanics. With its radical emphasis on the subject, QBism provides a welcome corrective to popular misrepresentations of the epistemological reflections of
Statistical Interpretation of Quantum Mechanics.
The published work for which the honor of the Nobel prize for the year 1954 has been accorded to me does not contain the discovery of a new phenomenon of nature but, rather, the foundations of a new
Entanglement, Information, and the Interpretation of Quantum Mechanics
This book explores the nature of quantum entanglement and quantum information and their role in the quantum world. Their relations to a number of key experiments and thought experiments in the
An introduction to QBism with an application to the locality of quantum mechanics
We give an introduction to the QBist interpretation of quantum mechanics, which removes the paradoxes, conundra, and pseudo-problems that have plagued quantum foundations for the past nine decades.
