Abstract
A novel hexagonal binary-decision-diagram (BDD) quantum logic circuit approach for III-V quantum large scale integrated circuits is proposed and its basic feasibility is demonstrated. In this approach, a III-V hexagonal nanowire network is controlled by Schottky wrap gates (WPGs) to implement BDD logic architecture by path switching. A novel single electron BDD OR logic circuit is successfully fabricated on a GaAs nanowire hexagon and correct circuit operation has been confirmed from 1.5 K to 120 K, showing that the WPG BDD circuit can operate over a wide temperature range by trading off between the power-delay product and the operation temperature.Keywords
