Dissipation and noise immunity in computation and communication

Abstract

Reversible computers which carry out each step without discarding information can, in principle, dissipate arbitrarily small amounts of energy per step if the computation is carried out sufficiently slowly. This has caused a re-examination of energy requirements in communication and measurement. There also, it is only those steps that discard information which have a lower limit on energy consumption. Such steps can be avoided in the transmission of information. © 1988 Nature Publishing Group.
