# Why I am not a QBist

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

- Philosophy

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

- Physics

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

- Philosophy
- 2019

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?

- Philosophy, Physics
- 2019

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…

Quantum Bayesianism as the basis of general theory of decision-making

- PhysicsPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2016

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)

- Philosophy
- 2016

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…

Can we close the Bohr–Einstein quantum debate?

- PhysicsPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2017

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

- Physics
- 2016

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

- Physics
- 2015

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).

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…
