Group of quantum information structures and networks

Institutions: Institute of Physics, Mathematical Institute
Group leader: Mário Ziman
Members: Anna Jenčová, Michal Sedlák, Vladimír Bužek, Daniel Reitzner, Anatolij Dvurečenskij
Focus: Analysis and optimalisation of mathematical structures and properties of quantum information (e.g. cloning, programming, estimations, discrimination)and identification and verification of quantum-information resources (e.g. entanglement, incompatibility, nonlocality). Design of multipartite protocols for secret-sharing and anonymous voting. Computation of quantum capacities for communication channels and structures of memory channels.
