Review paper on Quantum Bayesianism (QBism)?

As a collaborator of Fuchs, I will refrain from making my very first recommendation anything that we have coauthored. Instead, I'll note that the Stanford Encyclopedia of Philosophy has a pretty good article on QBism and related interpretations:

https://plato.stanford.edu/entries/quantum-bayesian/

This was written by Richard Healey, who is not a QBist but has an interpretational attitude that is in many ways QBism-adjacent. Being written for an SEoP audience, it is heavier on the philosophical matters and gives less time to the technical research that those matters have motivated.

If you want a whole book that you can carry around, Hans von Baeyer's QBism: The Future of Quantum Physics (Harvard University Press, 2016) is an accurate portrayal, pitched to the interested-layperson audience.

(And incidentally, on the topic of books, Persi Diaconis and Brian Skyrms recently released Ten Great Ideas about Chance, which lays out a school of thought about probability that is pretty much aligned with the one QBism adopts. Diaconis and Skyrms confine the quantum stuff to a single chapter, but they do recommend a David Mermin essay on QBism as good reading.)

Finally, if you want some writing straight from the source, I'll suggest the most recent essay by Fuchs, "Notwithstanding Bohr, the Reasons for QBism":

This is a longish piece ultimately published in a philosophy journal, but it splits the historical/philosophical and technical discussion fairly evenly.
