A generously funded Scientia Scholarship in experimental quantum physics is available at the Department of Physics at the University of New South Wales in Sydney, Australia.
The research project will investigate hole spins in quantum dots. In the past decade intense research has been devoted in trapping electrons trapped in semiconductor quantum dots, initially to study the fundamental properties of artificial atoms, and subsequently to use the spin of the electrons as the basis for quantum information technologies.
To date, almost all research has focussed on the properties of electrons in semiconductor quantum dots. However, very recent theoretical work suggests that using positively charged semiconductor holes, rather than negatively charged electrons, may bring significant advantages – as well revealing much unexplored new physics. This is because of the much stronger spin-orbit interaction that exists in holes than electrons, allowing the hole spins to be manipulated simply by applying an electric field. The PhD candidate will study holes trapped in semiconductor quantum dots, to perform all electrical control of hole spins, and to test if holes can make good quantum bits. Experiments will be conducted at ultra-low temperatures, using ultra-low noise electrical measurement and control techniques.
