Quantum Technologies Laboratory (QT LAB) Lab Leader: Prof. Konrad Banaszek

Within the QT Lab we develop new concepts for optical communication systems, building on recent advances in quantum information science and quantum optics. The central idea stems from reformulating the communication task as the identification problem for non-orthogonal quantum states describing individual inputs, rather than transmitting information in classical variables, such as the intensity or the phase, whose conventional measurements are bounded by standard quantum limits. This general approach, when implemented using the state-of-the-art methods for optical signal processing and characterization at the quantum level, opens up new ways to attain sub-shot-noise error rates as well as the superadditivity of accessible information through joint detection. The pursuit of these objectives is complemented by the development of realistic models for optical communication channels and the general analysis of resources in communication protocols.

Konrad Banaszek Prof.

Prof. Konrad Banaszek is the director of the Centre of Quantum Optical Technologies funded by the International Research Agenda Programme operated by the Foundation for Polish Science and hosted by the Centre of New Technologies, University of Warsaw. After receiving a PhD degree from the Faculty of Physics, University of Warsaw in 2000 he held postdoctoral fellowships at the University of Rochester (USA) and the University of Oxford (United Kingdom) followed by faculty appointments at the Nicolaus Copernicus University in Torun, Poland and the University of Warsaw. He is an author or a co-author of over 100 scientific articles dealing with various aspects of quantum technologies. Over the last decade he coordinated three projects funded by the 7th Framework Programme of the European Union and he realized two TEAM projects supported by the Foundation for Polish Science. In addition to his academic appointment at the University of Warsaw he also serves as the scientific coordinator of the QuantERA funding initiative, which groups 32 grant agencies from 26 countries and is coordinated by National Science Centre Poland.
