From Objective Amplitudes to Bayesian Probabilities
Quantum Physics

Abstract
We review the Consistent Amplitude approach to Quantum Theory and argue that quantum probabilities are explicitly Bayesian. In this approach amplitudes are tools for inference. They codify objective information about how complicated experimental setups are put together from simpler ones. Thus, probabilities may be partially subjective but the amplitudes are not.

10 pages, 2 figures. Invited paper presented at the International Conference on Foundations of Probability and Physics - 4 (Vaxjo University, Sweden, 2006). The various versions reflect my attempts to include the figures in the main body of the paper
