This chapter reviews the use of surface acoustic waves (SAWs) in an electron-spin based quantum state processor. A SAW-induced electric current of discrete single or controllable numbers of electrons, which can interact and become entangled, is discussed. Variable g-factor materials are proposed as a means of applying electrical control to single-qubit rotation and as a form of optical input and readout. The processing scheme can be used as a component in a quantum communications network.
