Single-Electron’s ‘spin’ In Silicon Will Lead to Revolutionary Quantum Chips

The three-year project, which has just received funding of £1M from the Engineering and Physical Sciences Research Council (EPSRC) aims to build the world’s first silicon-based integrated single-spin quantum bit system.

According to Professor Hiroshi Mizuta, Head of the Nano Research Group at the University’s School of Electronics and Computer Science (ECS), the new system will enable researchers working with silicon to initialise, manipulate and read single-electron’s ‘spin’ states rather than just charge states. In the past, it has been possible to capture just electronic charge. The advantage of employing spin rather than charge is that spin can maintain coherence and is hardly destroyed by interference in silicon or graphene.
