De Finetti Structures in Networks of Quantum Systems

Consider $N$ identical quantum systems at the vertices of a graph, interacting via pairwise edge couplings. We designate $K$ vertices as a system of interest $\mathrm S$ and the remaining $N-K$ as a reservoir $\mathrm R$. Under generic connectivity assumptions between $\mathrm S$ and $\mathrm R$, we show that for $N\to...
