Title: Quantum-informational convex structures
Duration: 01//01/2013 - 31/12/2015
Principal Investigator: Dr. Michal Sedlák
Project Goals: The primary objective of the project is an analysis of convex quantum structures such as, e.g., quantum combs, but also of convex structures of a wider class of probabilistic theories, e.g. for so-called process matrices. More specifically, the project aims at identification of extremal elements of the respective sets and the concept of joint measurability of their elements. This abstract investigation is motivated by applications in quantum information processing, which constitute the second objective of the present project. We will, for instance, find optimal designs for the so-called heralded protocols for quantum cloning and quantum learning of general quantum structures (not only states) in the respective part of the project. We will also investigate asymptotical properties of discrimination tasks, such as Chernoff bound for quantum channels.
