Chain Rules for Renyi Information Combining
Christoph Hirche, Xinyue Guan, Marco Tomamichel
Bounds on information combining are a fundamental tool in coding theory, in particular when analyzing polar codes and belief propagation. They usually bound the evolution of random…
Sequential Quantum Channel Discrimination
Yonglong Li, Christoph Hirche, Marco Tomamichel
We consider the sequential quantum channel discrimination problem using adaptive and non-adaptive strategies. In this setting the number of uses of the underlying quantum channel i…
Rényi Bounds on Information Combining
Christoph Hirche
Bounds on information combining are entropic inequalities that determine how the information, or entropy, of a set of random variables can change when they are combined in certain…
Convolutional Polar Codes
Andrew James Ferris, Christoph Hirche, David Poulin
Arikan's Polar codes attracted much attention as the first efficiently decodable and capacity achieving codes. Furthermore, Polar codes exhibit an exponentially decreasing block er…
