Quantum Technologies Laboratory

W Laboratorium Technologii Kwantowych rozwijane są nowe techniki dla optycznych systemów łączności wykorzystujące bieżące osiągnięcia optyki i informatyki kwantowej. Opracowywany jest schemat tzn. cyfrowych odcisków palców wykorzystujący interferencję wielofotonową, dzięki któremu zbędna jest stabilizacja fazy. Badana jest także propagacja sygnałów w obecności mechanizmów dekoherencji i wynikające stąd fundamentalne ograniczenia na przepustowość łączy optycznych.

Prof. Konrad Banaszek is currently 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.
