报告题目/Title：Resources in quantum information

报告摘要/Abstract：

Quantum information schemes provide advantages over their classical counterparts, like in quantum cryptography or quantum computing. But what is the origin of such advantages, or what are the important central elements to achieve advantages. We try to answer some of these questions using the general framework of resource theories. We show relations between quantum state resources like purity, coherence, discord, entanglement and discuss its necessity in certain quantum protocols. Besides resources in the quantum states a central role originates from resources due to the chosen quantum measurements. We investigate these resources and their quantification. We discuss its use in different scenarios, like in quantum steering, generating non-local correlations, stabilizer quantum computation and for proving security in quantum cryptography.

个人简介/Curriculum Vitae：

Hermann Kampermann received his phd in 2004 at the university of Duisburg in Germany on the topic Quantum information processing with nuclear magnetic resonance.He continued with a post-doc in the group of Dagmar Bruß at the Heinrich Heine University Düsseldorf, doing research on various concepts in quantum information theory. In 2014 he habilitated at the university of Düsseldorf with a thesis entitled Quantum states: correlations, optimal protocols and security. Since then he is private lecturer in the Institute of Theoretical Physics III in Düsseldorf. Hermann Kampermann has about 100 scientific publicationsin the research area of quantum information theory. His main research interests are on security in quantum cryptography,quantum networks, quantum correlations/entanglement, quantum measurement theory and undamental concepts in quantum information theory.
