The symmetric states on a quasi local C*–algebra on the infinite set of indices J are those invariant under the action of the group of the permutations moving only a finite, but arbitrary, number of elements of J. The celebrated De Finetti Theorem describes the structure of the symmetric states (i.e. exchangeable probability measures) in classical probability. 2007-03-13
More precisely, a quantum de Finetti theorem concerns the structure of a symmetric state ρ A 1…A n that is invariant under any permutations over the subsystems [17]. It tells how the reduced state ρ A 1…A k on a smaller number k

We present a new, elementary proof of de Finetti’s Theorem. The purpose of this paper is to make this theorem accessible to a broader community through an essentially self-contained proof. exchangeability lies in the following theorem. Theorem 2 (De Finetti, 1930s). A sequence of random variables (x1,x2,) is inﬁnitely exchangeable iﬀ, for all n, p(x1,x2,,x n) = Z Yn i=1 p(x i|θ)P(dθ), for some measure P on θ. If the distribution on θ has a density, we can replace P(dθ) with p(θ)dθ, but the theorem applies to a much of the de Finetti Theorem extends beyond the representation to the connection it a⁄ords between subjective beliefs and empirical frequencies.

Before stating a quantum de Finetti theorem for density operators, we should define permutation invari- ance for quantum states. A simple proof is given for de Finetti's theorem that every sequence of exchangeable 0-1 random variables is a proba- bility mixture of sequences of independent
