Abstract

Molecular electronics-based computation has attracted interest because the ultimate computational system would consist of logic devices that are ultra dense, ultra fast, and molecular-sized (PETT95, TERM97). One objective of current research is the fabrication and characterization of a molecular rectifier based on a single molecule (UEYA91, FISC94).

Molecular electronics is an interdisciplinary field, more than the most other ones, because knowledge is required from biology, chemistry, computer science and physics. Quantum-effect devices, which exploit the wave-like properties of electrons at the atomic level, are the subject of intense research at universities and corporate research institutes. That is because physics predicts quantum-effect devices should switch many hundreds of times faster, and consume much less energy, than today's transistors.

This paper gives an overview of the relations between quantum computer and molecular electronics. It also proposes some ideas for applications on such a new kind of computer.
