Craig S. Lent is the Frank M. Freimann Chair Professor of Engineering and Concurrent Professor of Physics at the University of Notre Dame. He received his PhD in Solid State Physics in 1984 from the University of Minnesota. His field of research is quantum devices and molecular-scale devices. The current research of his group focusses on the fundamental theoretical limits imposed by physics on computing devices. For the past several years his group has been investigating these questions in the context of a new transistor-less paradigm known as Quantum-dot Cellular Automata (QCA), developed at Notre Dame and now the subject of research worldwide.

Alexei O. Orlov received the M.S. degree in physics from the Moscow State University, Moscow, Russia, in 1983. He is currently a Research Professor at the University of Notre Dame, Notre Dame, IN, USA. From 1983 to 1993, he worked at the Institute of Radio Engineering and Electronics, Russian Academy of Sciences, Moscow, Russia. He received the Ph.D. degree in physics of semiconductors and dielectrics from the same Institute in 1990. During that time, he conducted research on mesoscopic and quantum ballistic effects in electron transport of GaAs field-effect transistors. He was a Visiting Fellow at the University of Exeter, U.K. in 1993, and joined the Department of Electrical Engineering, University of Notre Dame, in 1994. His research interests include experimental studies of mesoscopic, single-electron and molecular electronic devices and sensors, nanomagnetics, quantum-dot cellular automata and nanothermoelectrics. He has authored or coauthored more than 150 publications.

Wolfgang Porod currently is Frank M. Freimann Professor of Electrical Engineering at the University of Notre Dame. He received his Diplom (M.S.) and Ph.D. degrees from the University of Graz, Austria, in 1979 and 1981, respectively. After appointments as a postdoctoral fellow at Colorado State University and as a senior research analyst at Arizona State University, he joined the University of Notre Dame in 1986 as an Associate Professor. He also has served as the founding Director of Notre Dame's Center for Nano Science and Technology (NDnano). His research interests are in the area of nanoelectronics and nanomagnetics, with an emphasis on new circuit concepts for novel devices. He has authored some 600 publications and presentations. He is a Fellow of the IEEE and he has served (2002-2003) as the Vice President for Publications on the IEEE Nanotechnology Council. Over the years, he has been active in organizing Conferences, Special Sessions and Tutorials, and as a speaker in IEEE Distinguished Lecturer Programs.

Gregory L. Snider received his Ph.D. at the University of California, Santa Barbara in 1991, and was a post-doc at Cornell University. He joined the University of Notre Dame in 1994. His research focuses on the design, fabrication, and measurements of micro and nanoelectronic devices and circuits. In the micro regime, his group works on CMOS circuits to study dissipation in computation, as well as to interface CMOS and nano devices. On the nano side, his research focuses on single-electron devices including Quantum-dot Cellular Automata (QCA) and molecular devices. He is author or co-author of approximately 300 publications and conference presentations. He has served as the Associate Chair for Graduate Studies in the Department of Electrical Engineering, an Associate Editor of the IEEE Transactions on Electronic Devices, and is a Fellow of the IEEE.

Provides an in-depth investigation of the Landauer principle and how it relates to the possible existence of lower bounds on dissipation in computation

Gathers together both sides of the discussion: those who agree with Landauer and his conclusions, and those who think that Landauer was not correct, offering fresh perspective on the issues in the new light of experiments

Offers insight into the future of silicon CMOS and the limits if any to progress in computation related to energy dissipation
