Abstract: A novel approach for quantum logic circuits is described. In this approach, graph-based circuits are directly constructed on nanowire networks and controlled by multiple quantum wire branch switches. Potential advantages of the approach are briefly discussed. A novel GaAs branch switch using a nano-scale Schottky wrap gates (WPGs) on etched AlGaAs/GaAs nanowire was fabricated and its basic control characteristics were investigated. WPG realizes tight gate control of quantum transport near wire pinch off and shows clear conductance quantization at low temperatures. Simple circuits for BDD path switching and AND logic function were then fabricated, and they showed correct operation at low temperature. They could be operated at room temperature by increasing power consumption.
