Funded PhD Project (European/UK Students Only)
About the Project
A 3.5 year PhD position is available in in the Ion Quantum Technology Group in the Sussex Centre for Quantum Technologies in the Department of Physics & Astronomy at the University of Sussex. The position is part of the UK National Quantum Technologies programme and ideally you will be able to start in early 2019.
We recently invented a method whereby quantum gates with trapped ions are executed by the application of voltages to a microchip in the presence of a few global radiation fields analogous to the operation of transistors in a classical computer. We have already accomplished two-qubit quantum gates with fidelities close to the fault-tolerant threshold. We are now working towards increasing two-qubit gate fidelities above 99.9% and reduce gate times down between 10 - 100 μs. In order to achieve that, we are raising magnetic field gradients on the chip while increasing parameter fluctuation resilience and resilience to noise via a number of coherent control methods such as double dressing. We are also developing subsystems for this purpose such as stable voltage sources, microwave amplification and current sources together with industrial collaborators. The aim of this project is to combine the work of our industry collaborators with coherent control methods to obtain ultimate gate fidelities and gate speeds.
The Ion Quantum Technology Group is one of the world’s leading centres for the implementation of trapped-ion quantum computing and simulation. The group is part of the UK Quantum Technology Hub on Networked Quantum Technologies and the UK Quantum Technology Hub for Sensors and Metrology. The group currently spans 7 staff scientists, 2 electronic engineers, 14 PhD students and 6 undergraduate students.
The city of Brighton & Hove has everything - sun, sea, brilliant clubs, great places to eat, fabulous shops, a truly cosmopolitan vibe and is located only 50min from central London. Located on the beach, Brighton boasts beautiful seaside views and beaches, boating, sports and beach activities. The South Downs provide breathtaking views, tranquil walks and plenty of opportunities for mountain biking, hiking or picnics.
