Classical analog of the quantum marginal problem
Original language description
We construct a classical cryptographic analog of multipartite entanglement which can be verified solely from separable marginals. That is a set of marginal classical probability distributions carrying no secret correlations, which are compatible only with a joint distribution containing secret correlations. This demonstrates that the emergent correlation properties do not exist only in the quantum world. Viewed from a different perspective, our result reveals another possible application of the quantum marginal problems in that they can help us to design and solve interesting classical marginal problems.
