Welcome to Frontiers in Nanocomputing, a seminar series that focuses on systems issues for nanoelectronics. Our topic was Fundamental Limits of Digital Computation. The questions to each speaker were: What are the fundamental limits? How close are we to those limits? How relevant are they to real technologies? How close will CMOS eventually get? And finally: What are the most promising alternatives to CMOS? The topic of reversible computing was one that came up in each of the four talks. Video streams and presentation slides are available for each seminar.

We thank the presenters for a set of excellent talks and for being so responsive to our questions and to the issues that other speakers raised. Our hope is that this series of talks stimulates discussions that shed some real light on these important issues.

  1. Nanoelectronic Scaling Tradeoffs: What does Physics Have to Say?

    23 Sep 2003 | Presentation Materials | Contributor(s): Victor Zhirnov

    Beyond CMOS, several completely new approaches to information-processing and data-storage technologies and architectures are emerging to address the timeframe beyond the current SIA International Technology Roadmap for Semiconductors (ITRS). A wide range of new ideas have been proposed for...

  2. Quantum-dot Cellular Automata

    24 Nov 2003 | Online Presentations | Contributor(s): Craig S. Lent

    The multiple challenges presented by the problem of scaling transistor sizes are all related to the fact that transistors encode binary information by the state of a current switch. What is required is a new paradigm, still capable of providing general purpose digital computation, but which can...

  3. Digital Electronics: Fundamental Limits and Future Prospects

    20 Jan 2004 | Online Presentations | Contributor(s): Konstantin K. Likharev

    I will review some old and some recent work on the fundamental (and not so fundamental) limits imposed by physics of electron devices on their density and power consumption.

  4. A Personal Quest for Information

    19 Feb 2004 | Online Presentations | Contributor(s): Vwani P. Roychowdhury

    This talk will report results and conclusions from my personal investigations into several different disciplines, carried out with the unifying intent of uncovering some of the fundamental principles that govern representation, processing, and the communication of information. The specific...
