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…
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…
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…
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)…
