High Speed Quantum Device and Circuits: Modeling and Design. Phase 1

Abstract

This document summarizes work carried out under a U.S. Navy SBIR study, Topic N99-02. The goal of the study was to develop a robust, portable, user-friendly, validated quantum device algorithm for designing tunneling devices, in particular resonant tunneling devices, for realistic present, near future and future applications. Successful algorithm development based on the space and time dependent Wigner equation was undertaken with the result that SRA has, in place, a transient algorithm for calculating the switching properties of resonant tunneling devices under a variety of conditions. The algorithm includes design information with respect to contacts, dissipation and the external circuit. The effects of noise were briefly studied, and recommendations were made for further work to permit the implementation of the algorithm for the design of a 100+GHz clock.
