Gaussian multipartite bound information
Original language description
We demonstrate the existence of Gaussian multipartite bound information which is a classical analog of Gaussian multipartite bound entanglement. We construct a tripartite Gaussian distribution from which no secret key can be distilled, but which cannot be created by local operations and public communication. Further, we show that the presence of bound information is conditional on the presence of a part of the adversary's information creatable only by private communication. Existence of this part of theadversary's information is found to be a more generic feature of classical analogs of quantum phenomena obtained by mapping of nonclassically correlated separable quantum states.
