Tightening the Consistency of Quantum Bayesianism

Quantum Bayesianism is an effort to interpret all the probabilities arising in quantum theory (our most accurate physical theory to date, the one ultimately responsible for almost all of modern technology) in terms of the Bayesian conception of probability – that probabilities quantify subjective degrees of belief, rather than objective features of nature.  This way of looking at quantum theory greatly relieves many of the conundrums traditionally associated with the theory, and also gives a very natural framework for many of the recent developments in quantum information processing and computing.  For this project, we have gathered the leading physicists, philosophers, and mathematicians associated with the movement to fine-tune the view as far as possible.
