Are Non-Boolean Event Structures the Precedence or Consequence of Quantum Probability?
Christopher A. Fuchs, Blake C. Stacey
In the last five years of his life Itamar Pitowsky developed the idea that the formal structure of quantum theory should be thought of as a Bayesian probability theory adapted to t…
Discrete Wigner Functions from Informationally Complete Quantum Measurements
John B. DeBrota, Blake C. Stacey
Wigner functions provide a way to do quantum physics using quasiprobabilities, that is, "probability" distributions that can go negative. Informationally complete POVMs, a much you…
Ideas Abandoned en Route to QBism
Blake C. Stacey
The interpretation of quantum mechanics known as QBism developed out of efforts to understand the probabilities arising in quantum physics as Bayesian in character. But this develo…
Sporadic SICs and Exceptional Lie Algebras
Blake C. Stacey
Sometimes, mathematical oddities crowd in upon one another, and the exceptions to one classification scheme reveal themselves as fellow-travelers with the exceptions to a quite dif…
On QBism and Assumption (Q)
Blake C. Stacey
I correct two misapprehensions, one historical and one conceptual, in the recent literature on extensions of the Wigner's Friend thought-experiment. Perhaps fittingly, both concern…
Lüders Channels and the Existence of Symmetric Informationally Complete Measurements
John B. DeBrota, Blake C. Stacey
The Lüders rule provides a way to define a quantum channel given a quantum measurement. Using this construction, we establish an if-and-only-if condition for the existence of a …
