QBism

QBism or Quantum Bayesianism, is an interpretation of quantum mechanics (see what I say about it there) championed by Christopher Fuchs, who provides the following list of material as an introduction [1] (he provides the arXiv versions, while my archivist habits urge me to update to their published versions when available):

• QBism: Quantum theory as a hero's handbook. C. A. Fuchs and B. C. Stacey in Proceedings of the International School of Physics "Enrico Fermi" 🕮Foundations of Quantum Theory 197:133 (2016).
• An introduction to QBism with an application to the locality of quantum mechanics. C. A. Fuchs, N. D. Mermin and R. Schack in Am. J. Phys. 82:749 (2014).
• Interview with a Quantum Bayesian. C. A. Fuchs in arXiv:1207.2141 (2012). — This might be justified as an arXiv since the original (Elegance and Enigma) has the replies scattered with other interviewees (which also has its charm).
• On Participatory Realism. C. A. Fuchs in 🕮Information and Interaction: Eddington, Wheeler and the Limits of Knowledge. Ch. 7 (2017).
• Nothwithstanding Bohr, the Reasons for QBism. C. A. Fuchs in Mind Matt. 15:245 (2017).
• Quantum-Bayesian coherence. C. Fuchs and R. Schack in Rev. Mod. Phys. 85:1693 (2013).
• Why QBism is not the Copenhagen interpretation and what John Bell might have thought of it. N. D. Mermin in arXiv:1409.2454 (2014).
