In 1961/1962 this author proposed that the uncertainty principle of quantum mechanics
imposes fundamental limitations upon computers (Bremermann, 1962a, 1962b). As Von …

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 …

T hpheoretical computer scientists, like their counterparts in physics, suffer and benefit from
a high level of intellectual machismo. They believe they have some of the biggest brains …

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 …

The effect of the quantum nature of matter on the maximum informationprocesssing
potentialities is considered. It is shown that the degeneracy of the energy levels of a physical …

Using atoms as digital bits will start a completely new era in computer design. Atoms cannot
be simply manipulated and used like the bits built with transistors. The behavior of matter on …

In this chapter, the authors discuss a part in an effort to analyze the physical limitations of
computers due to the laws of physics. It is a result of computer science that a universal …

The physical foundation of a computer, specifically, the thermodynamic and quantum
mechanical limits, has been an interesting theoretical subject for many years. The …
