摘要
A new approach to the implementation of certain logical functions in quantum-dot gates for single-electron computing is proposed. It is shown that placing a gate in a uniform external magnetic field allows one to construct gates with 1) symmetric physical truth tables and 2) large (in some cases close to saturated) absolute magnitude of the average spin at the output dots. Thus two serious obstacles are removed which otherwise could present a problem in the fabrication of a set of coupled quantum-dot gates. (C) 1996 American Institute of Physics.
