Quantum Theory of Shannon

The Shannon project focuses on searching for the fundamental limits associated with the limited use of quantum resources together with the coding techniques that can address such limits. In a generic model communication system, legitimate transmitters and receivers communicate in the presence of third parties who listen to the information transmitted through the channel. This transmission scheme, well known in a classical context, remains unexplored in the quantum domain, especially in the case of transmission through a single channel use, which in fact it will be an objective to be pursued within this project.

Javier Rodríguez Fonollosa

Javier Rodríguez is a Professor at the Polytechnic University of Catalunya since 2003 and is currently part of the Signal Processing and Communications group (https://spcom.upc.edu/en). He got his PhD from Northeastern University in 1993 and then he joined the Signals and Communications Theory group at the UPC, which he led between 2006 and 2010. Between 2010 and 2014 he was director of the Electronic Technologies and Communications (TEC) area of ​​the National Research Plan. Since 1995 he has participated and led multiple European projects (TSUNAMI (II), SUNBEAM, METRA, I-METRA, SURFACE) and national Consolider projects (COMONSENS). His research covers different areas of Shannon’s quantum theory, from fundamental limits of compensation in single-plane communication to perfect and quasi-perfect quantum channel codes.

UAB

Andreas Winter

Andreas Winter is an ICREA professor and has been part of the Quantum Information group at the Autonomous University of Barcelona since 2012. He obtained his PhD from Bielefeld University in 1999. In 2001 he joined the Quantum Information group in Bristol as a postdoctoral fellow, became Professor of Applied Mathematics in 2003 and Professor of Information Physics in 2006. His research focus on quantum information, especially the Shannon’s quantum theory, whose objective is to incorporate theoretical ideas of information into physics. He also investigates the interaction between classical and quantum information, as well as additivity and non-additivity of quantum channel capacities, quantum data compression, and zero-error quantum communication.
