Abstract

A d-dot is a superconducting composite structure of d- and s-wave superconductors, which shows spontaneous half-quantized magnetic fluxes. We developed numerical method to analyze the time development of these spontaneous magnetic fluxes, based on the two-components Ginzburg-Landau equation. The d-dot can be used as an element of quantum dot cellular automata logic gates. We show a simulation, which demonstrates the transfer of information between two d-dot's.
