Richard Healey: Correlations, probabilities and quantum states

In Bananaworld Jeffrey Bub advocates what he calls an information-theoretic interpretation of quantum theory. This may usefully be compared to the pragmatist approach I have been developing in recent years. We agree on many key issues, standing shoulder to shoulder against realist as well as instrumentalist enthusiasts. But I cannot accept some things he says in his book and remain puzzled by others. After locating our common ground I’ll focus on some points on which I think we disagree. Most of these have to do with the nature and function of quantum states and probabilities and what these have to do with information.
