Demosthenes Ellinas is a Professor in The School of ECE of Technical University of Crete. He did postgraduate studies at the International School of Advance Studies (SISSA) in Trieste Italy and at University of Helsinki in Finland, from where he obtained his PhD degree in Theoretical Physics (1990). He spend two years as postdoctoral fellow at University of Valencia in Spain. His research activity at that time was extended to applications of group theoretical methods – Lie groups, Hopf algebras etc – to various physical problems. His teaching experience includes teaching positions in the University of Helsinki, the Vaasa Institute of Technology in Finland, the University of Crete, Department of Mathematics, the Technical University of Crete, Department of Sciences and the Athens University of Economics and Business, Department of Informatics. His current research interests and work are in the area of Quantum Information and Computation, with emphasis on Quantum Algorithms. He has made extended visits as research fellow to The University of Queensland, Department of Mathematics, in Brisbane Australia (2000-10). He has taken sabbatical leaves from TUC as invited visiting scholar to the Engineering Quantum Systems Centre of Excellence of Macquarie University, Sydney, the School of Mathematics and Physics of University of Tasmania, the School of Mathematics and Physics of The University of Queensland, in Australia, to the University of Helsinki and to the Centre for Quantum Technologies in Singapore. He has been also collaborating with teams in University of Glasgow, the University of York, and the University of Leeds in UK, on topics such as topological quantum computing and twisted light-matter interaction and applications. He has co-organized workshops on various topics, most recently on the topic of “Quantum Matter”. He has also edit and co-edit special issues and volume on topics such as “Chaos”, “Quantum Computation and Information: Multi-Particle Aspects”, and “Quantum Search: Quantization, Applications and Ramifications”. Dr Ellinas enjoys walking.
