The structure of Renyi entropic inequalities
Noah Linden, Milán Mosonyi, Andreas Winter
We investigate the universal inequalities relating the alpha-Renyi entropies of the marginals of a multi-partite quantum state. This is in analogy to the same question for the Shan…
Quantum rate distortion coding with auxiliary resources
Mark M. Wilde, Nilanjana Datta, Min-Hsiu Hsieh +1
We extend quantum rate distortion theory by considering auxiliary resources that might be available to a sender and receiver performing lossy quantum data compression. The first se…
Identification Via Quantum Channels
Andreas Winter
We review the development of the quantum version of Ahlswede and Dueck's theory of identification via channels. As is often the case in quantum probability, there is not just one b…
Quantum Hypergraph States
M. Rossi, M. Huber, D. Bruß +1
We introduce a class of multiqubit quantum states which generalizes graph states. These states correspond to an underlying mathematical hypergraph, i.e. a graph where edges connect…
Robust weak-measurement protocol for Bohmian velocities
F. L. Traversa, G. Albareda, M. Di Ventra +1
We present a protocol for measuring Bohmian - or the mathematically equivalent hydrodynamic - velocities based on an ensemble of two position measurements, defined from a Positive…
Relative entropy and squashed entanglement
Ke Li, Andreas Winter
We are interested in the properties and relations of entanglement measures. Especially, we focus on the squashed entanglement and relative entropy of entanglement, as well as their…
