Before stating a quantum de Finetti theorem for density operators, we should define permutation invari- ance for quantum states.

In probability theory, de Finetti's theorem states that exchangeable observations are conditionally independent relative to some latent variable. An epistemic probability distribution could then be assigned to this variable. It is named in honor of Bruno de Finetti. Contents.

We include this in a course on statistical inference, because the theorem is a cornerstone of of Bayesian statistical inference, and is a critique of objectivistic modes of statistical inference. Timo Koski Matematisk statistik 20.01.2010 5 / 21 de Finetti’s Theorem de Finetti (1931) shows that all exchangeable binary sequences are mixtures of Bernoulli sequences: A binary sequence X 1,,X n, is exchangeable if and only if there exists a distribution function F on [0,1] such that for all n p(x 1,,x n) = Z 1 0 θtn(1−θ)n−tn dF(θ), where p(x 1,,x n) = P(X 1 = x 1,,X n = x n) and t n = P n i=1 x i. 2019-08-01 In probability theory, de Finetti's theorem states that exchangeable observations are conditionally independent given some latent variable to which an epistemic probability distribution would then be assigned.

The theorem postulates that such a sequence is uniquely representable as a mixture of iid sequences of Bernoulli random variables. de Finetti’s complete bibliography can be found in Daboni (1987). Many recent developments of de Finetti’s work are mentioned here and brie y described, as are the lengthier developments, in note within the text.

The Backward Martingale convergence theorem allows to prove a strong law of large 2019-12-05 A famous theorem of De Finetti (1931) shows that an exchangeable sequence of \$\{0, 1\}\$-valued random variables is a unique mixture of coin tossing processes. Many generalizations of this result have been found; Hewitt and Savage (1955) for example extended De Finetti's theorem to arbitrary compact state spaces (instead of just \$\{0, 1\}\$).
