I consider the "Quantum Bayesian" view of quantum theory as expounded in a 2006 paper of Caves, Fuchs, and Schack. I argue that one can accept a generally personalist, decision-theoretic view of probability, including probability as manifested in quantum physics, while nevertheless accepting that in some situations, including some in quantum physics, probabilities may in a useful sense be thought of as objectively correct. This includes situations in which the ascription of a quantum state… 

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

Von Neumann was not a Quantum Bayesian

TLDR
This essay explores how such a claim that John von Neumann was the ‘first quantum Bayesian’ is, historically speaking, unsupported.

The classical limit of a physical theory and the dimensionality of space

TLDR
It is shown that as long as the interaction is pairwise, this is impossible, and quantum mechanics and the three-dimensional space remain the only solution, however, having multi-particle interactions and a generalized notion of “classical field” may open up such a possibility.

Teleportation in General Probabilistic Theories

In a previous paper, we showed that many important quantum information-theoretic phenomena, including the no-cloning and no-broadcasting theorems, are in fact generic in all non-classical

We prove generic versions of the no-cloning and no-broadcasting theorems, applicable to essentially {\em any} non-classical finite-dimensional probabilistic model that satisfies a no-signaling
