PhD project

At Sussex we have recently realized a new generation of ion chips which incorporate an X-junction ion trap array as well as integrated current carrying wires required to implement high-fidelity 2-qubit gates. In order to execute quantum algorithm, we need to demonstrate fast ion transport operations making use of the idea of diabatic shuttling. We are developing diabatic shuttling as part of a collaboration with Imperial College London. In diabatic ion transport makes use of phase sensitive control of the trapping potentials in order to allow for fast transport without injecting kinetic energy to the ion. Sympathetic cooling is a key feature of an ion trap quantum computer. As part of this studentship, the student will demonstrate sympathetic cooling with Barium ions. The student will then introduce a set of ion transport protocols where they will demonstrate diabatic shuttling followed by sympathetic cooling. The project will culminate in the execution of a quantum algorithm including gate execution, diabatic shuttling and sympathetic cooling

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 Hub on Quantum Computing and Simulation. The group currently spans 6 Postdoctoral Fellows, 14 PhD students, the Senior Scientist and the Head of Group.


Applicants must hold, or expect to hold, at least a UK upper second class degree (or non-UK equivalent qualification) in Physics, or a closely-related area, or else a lower second class degree followed by a relevant Master's degree.Only UK
