Analog Computing for the 21st Century

Abstract

Many people think of analog computing as a historic dead-end in computing. In fact, nothing could be further from the truth as analog computing - together with quantum computing - has the potential to bring computing to new levels with respect to raw computational power and energy efficiency. The following paper explains the limits of digital computers, gives a quick introduction to analog computing in general, and shows a number of recent developments that will change the way we think about computers in the next few years.
