We explore the use of the split-gate method to implement coupled-electron waveguides (CEWs), for possible application as a scalable qubit in quantum computing. Electron switching in these structures is found to be strongly influenced by structural asymmetry, which appears to arise quite naturally when using the split-gate method to implement complicated nanostructures. The consequences of the asymmetry are shown to depend strongly on the manner in which the input and output ports of the device…
