On the quantum, classical and total amount of correlations in a quantum state
Berry Groisman, Sandu Popescu, Andreas Winter
We give an operational definition of the quantum, classical and total amount of correlations in a bipartite quantum state. We argue that these quantities can be defined via the amo…
Optimal superdense coding of entangled states
Anura Abeyesinghe, Patrick Hayden, Graeme Smith +1
We present a one-shot method for preparing pure entangled states between a sender and a receiver at a minimal cost of entanglement and quantum communication. In the case of prepari…
Aspects of generic entanglement
Patrick Hayden, Debbie W. Leung, Andreas Winter
We study entanglement and other correlation properties of random states in high-dimensional bipartite systems. These correlations are quantified by parameters that are subject to t…
A new inequality for the von Neumann entropy
Noah Linden, Andreas Winter
Strong subadditivity of von Neumann entropy, proved in 1973 by Lieb and Ruskai, is a cornerstone of quantum coding theory. All other known inequalities for entropies of quantum sys…
On the distributed compression of quantum information
Charlene Ahn, Andrew Doherty, Patrick Hayden +1
We consider the problem of distributed compression for correlated quantum sources. The classical version of this problem was solved by Slepian and Wolf, who showed that distributed…
