The question of the energy dissipation in the computational process is considered. Contrary
to previous studies, dissipation is found to be an integral part of computation. A …

Computers may be thought of as engines for transforming free energy into waste heat and
mathematical work. Existing electronic computers dissipate energy vastly in excess of the …

A recentLetter in this journal'(henceforth PGFP) reasserts, with the help of some plausible
but informal arguments, a view once widely held but subsequently refuted, viz., that …

The letter by Porod et al.'(PGFP for short) purports to show results that disagree with
previous studies on the issue of nondissipative computation. This letter is very misleading …

This work is a part of an effort to analyze the physical limitations of computers due to the
laws of physics. For example, Bennett'" has made a careful study of the free energy …

This book is an introduction to the computational methods used in physics and other
scientific fields. It is addressed to an audience that has already been exposed to the …

Are principles of information processing necessary to demonstrate the consistency of
statistical mechanics? Does the physical implementation of a computational operation have …

Algorithmic randomness provides a rigorous, entropylike measure of disorder of an
individual, microscopic, definite state of a physical system. It is defined by the size (in binary …

Interest in the physical limitations of the computation process has been increasing in recent
years.'.'Landauer3 “has discussed this subject extensively, particularly from the viewpoint of …

A lower bound on the amount of energy needed to carry out an elementary logical operation
on a quantum computer, with a given accuracy and in a given time, is derived. The bound …
