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”).
Prof. Ford will introduce these topics and will describe his work on
transferring single electrons between dots using sound waves travelling
along a surface.
