“…It and Bohrian thought are two detectably distinct examples of participatory realism [30,50]. In fact, QBism has drawn as much upon the thinking of Einstein as upon Bohr [51], a point that our discussion of the locality desideratum suggested. As Fuchs declared [29], "When Einstein was right, he was really right!"…”

In 1996, N. David Mermin proposed a set of desiderata for an understanding of quantum mechanics, the "Ithaca Interpretation". In 2012, Mermin became a public advocate of QBism, an interpretation due to Christopher Fuchs and Rüdiger Schack.Here, we evaluate QBism with respect to the Ithaca Interpretation's six desiderata, in the process also evaluating those desiderata themselves. This analysis reveals a genuine distinction between QBism and the IIQM, but also a natural progression from one to the other.

“…This formula is the Law of Total Probability, and it expresses the intuition that classical uncertainty is ignorance of a system's "physical condition" (to use Einstein's terminology [41]) or "ontic state" (in a more modern turn of phrase). We will show that the function µ cannot be of this form, and that the correct quantum form of µ follows from an expression of quantum vitality.…”

I summarize a research program that aims to reconstruct quantum theory from a fundamental physical principle that, while a quantum system has no intrinsic hidden variables, it can be understood using a reference measurement. This program reduces the physical question of why the quantum formalism is empirically successful to the mathematical question of why complete sets of equiangular lines appear to exist in complex vector spaces when they do not exist in real ones. My primary goal is to clarify motivations, rather than to present a closed book of numbered theorems, and consequently the discussion is more in the manner of a colloquium than a PRL.

“…QBism does not have, for example, Bohr's emphasis on "ordinary language" [11], whatever that might mean. Nor does it have the quantum-classical cut of Heisenberg, the classical laboratory equipment of Landau and Lifshitz [12], the public experimental records of Pauli [13], the essentially ontic state vectors of early Bohm [14], or the frequentism of early von Neumann [15].…”

“…In quantum theory, there is no analogue of this. (Emphasizing this point of disanalogy is another way QBism distinguishes itself from Bohr [11].) RQM tries to invent one, but the attempt flounders.…”

We answer several questions that have been Frequently Asked about QBism. These remarks (many of them lighthearted) should be considered supplements to more systematic treatments by the authors and others.QBism \"kyü-bi-z@m\ n. an interpretation of quantum mechanics in which the ideas of agent and experience are fundamental. A "quantum measurement" is an act that an agent performs on the external world. A "quantum state" is an agent's encoding of her own personal expectations for what she might experience as a consequence of her actions. Moreover, each measurement outcome is a personal event, an experience specific to the agent who incites it. Subjective judgments thus comprise much of the quantum machinery, but the formalism of the theory establishes the standard to which agents should strive to hold their expectations, and that standard for the relations among beliefs is as objective as any other physical theory.

Abstract: Notwithstanding its great influence in modern physics, the EPR thought-experiment has been explained incorrectly a surprising number of times.
