A three-year PhD position is available in the Ion Quantum Technology Group in the Department of Physics & Astronomy at the University of Sussex. The position is funded in conjunction with an EPSRC funded £1.4M Leadership fellowship for the development of quantum technology with nanofabricated ion trap chips.

Application deadline: January 30, please apply preferentially by 20 December 2012 (applications after this deadline until January 30 will be consider if position is not filled)

Research in novel quantum technologies will likely lead to step changing innovations which will affect many areas of modern sciences. Implementing such technologies with trapped ions quantum bits has been widely accepted as one of the most promising pathways. The aim of this studentship is to produce advanced nano-fabricated ion chips and to carry out entanglement experiments with trapped ions in order to build a practical ion trap quantum computer.

One of the main aims of the project is to develop ion chips that feature on-chip digital signal processing and specialized architectures for large scale entanglement generation. Furthermore, you will also carry out studies to implement on-chip cavities, fibre interconnects to the ion trap array for advanced ion quantum state detection capabilities and other advanced features. You will create microchips for large scale entanglement creation of trapped ions on a chip. Once suitable ion chips are available you will carry out entanglement experiments and create practical quantum simulators.

You will learn all the experimental skills and theoretical background needed in this emerging field of science. Some of the skills you will acquire include nano-fabrication, lasers and optics, ultra-high vacuum techniques, quantum information science, electronics and many other skills. You will spend your first year primarily at Sussex where you will become an expert in ion trapping. Following that you will spend some periods of time at clean room facilities carrying out microfabrication in state-of-the-art clean rooms. Once the first chips have been created, you will carry out quantum information experiments with trapped ions. The position consists of current UK/EU fees and a yearly stipend of £ 13590 which can be supplemented by tutoring.
