Semiconductor fabrication techniques allow researchers to make devices containing just a single electron, resembling an artificial atom, with quantised energy levels, but with far more control than in a real atom. The long-term goal is to make a quantum computer using a set of these “quantum dots”, each holding a quantum bit of information (“qubit”). I will introduce these topics and will describe our work on transferring single electrons between dots using sound waves travelling along a surface. I will also present our recent work on generating single photons from these single electrons.
