Unknown quantum states: The quantum de Finetti representation. C. Caves, C. Fuchs and R. Schack in J. Math. Phys. 43:4537 (2002). What the paper says!?
Points at interesting papers, including Refs. [1][2]. In particular, they describe Jaynes's book on probability as follows: «This huge book was unfortunately never finished due to Prof. Jaynes’ death in 1998. Nevertheless, it stands as perhaps the most complete and persuasive document in the field.»
We also came to the conclusion that questions like «"Which physical resources actually make quantum computation efficient?" start to feel tractable (and even connected) from [the] perspective» of the Bayesianist interpretation of the theory.
