Some properties and applications of the new quantum -divergences
Salman Beigi, Christoph Hirche, Marco Tomamichel
Recently, a new definition for quantum -divergences was introduced based on an integral representation. These divergences have shown remarkable properties, for example when inve…
Quantum Sequential Hypothesis Testing
Esteban Martínez-Vargas, Christoph Hirche, Gael Sentís +4
We introduce sequential analysis in quantum information processing, by focusing on the fundamental task of quantum hypothesis testing. In particular our goal is to discriminate bet…
Discrimination and estimation of incoherent sources under misalignment
J. O. de Almeida, J. Kołodyński, C. Hirche +2
Spatially resolving two incoherent point sources whose separation is well below the diffraction limit dictated by classical optics has recently been shown possible using techniques…
From asymptotic hypothesis testing to entropy inequalities
Christoph Hirche
This thesis addresses the interplay between asymptotic hypothesis testing and entropy inequalities in quantum information theory. In the first part of the thesis we focus on hypoth…
Convexity and Operational Interpretation of the Quantum Information Bottleneck Function
Nilanjana Datta, Christoph Hirche, Andreas Winter
In classical information theory, the information bottleneck method (IBM) can be regarded as a method of lossy data compression which focusses on preserving meaningful (or relevant)…
Amortized Channel Divergence for Asymptotic Quantum Channel Discrimination
Mark M. Wilde, Mario Berta, Christoph Hirche +1
It is well known that for the discrimination of classical and quantum channels in the finite, non-asymptotic regime, adaptive strategies can give an advantage over non-adaptive str…
