Saving Energy with Future Quantum Technologies

Abstract

According to some reports, ICT comes at the cost of electricity consumption worldwide which is at a par with the total electrical energy consumption of Japan plus Germany, of the order of 1500 TWH per year. This all may get worse as the Internet of Things hits the market. Thus we need to consider new technologies that may reduce this number considerably. We will discuss two complementary directions for substantially reducing the energy consumption of communication systems: one is to use spin properties of particles, and the other is to use quantum wall effects in neuromorphic digital systems. We will try to present the related concepts using formalisms that are familiar to communication engineers, and describe the challenges that arise in each case. The ideas in this presentation come from our recent papers that appeared in journals such as IEEE Access, IEEE Trans. on Emerging Topics in Computing, ACM Performance Evaluation Review, and Energies.

Brief Bio

Professor Gelenbe is a Fellow of ACM and IEEE, the speaker is the Dennis Gabor Professor in the Electrical and Electronic Engineering Department at Imperial College, London, and Head of its Intelligent Systems and Networks Group. He received the ACM-SIGMETRICS Life-time Achievement Award in 2008 for pioneering work in computer and network performance evaluation. He was elected to the Royal Academy of Sciences, Arts and Letters of Belgium (2015), the Science Academies of Hungary (2010), Poland (2013) and Turkey (2007), and the 350 member French National Academy of Engineering (2008). He is ranked among the "Top 50 PhD advisers worldwide and all times in the mathematical sciences" by the American Mathematical Society's Math Genealogy Project, for graduating 73 PhDs including 17 women; three of his former PhD students are members of their national academies and several are CEOs or CTOs in major corporations. He was awarded Knight of the Legion of Honour (2014) and Officer of Merit (2002) by the President of France, and Commander of Merit (2005) by the President of Italy. His other awards include three honorary doctorates ("honoris causa"), the Dennis Gabor Award of the Hungarian Academy of Sciences (2013), the Oliver Lodge Medal of the IET (2010), and the Grand Prix France Telecom of the French Academy of Sciences (1996). His research is currently funded by EPSRC (similar to NSF), the European Union, and industry.
