PhD Studentship in Entanglement swapping in a multi-module quantum computer (2023)
A 3.5 year PhD is available in the Ion Quantum Technology Group in the Sussex Centre for Quantum Technologies at the University of Sussex. The position is part of the UK National Quantum Technologies programme. You should have a physics, or related degree. It may include collaborative work with the Universal Quantum Group of companies based close to Brighton (UK), Hamburg (Germany) and Silicon Valley (California).
What you get
Fully-paid tuition fees for three and a half years at the home fee status.
A tax-free bursary for living costs for three and a half years (£17,668 per annum in 2022/23).
Additional financial support is provided to cover short-term and long-term travel.
If you are not a UK national, nor an EU national with UK settled/pre-settled status, you will need to apply for a student study visa before admission.
Type of award
Postgraduate Research
PhD project
Having a modular quantum computer architecture is critical as it is impossible to fit sufficiently many qubits on a single quantum computing module. We recently succeeded in demonstrating a new modular quantum computing architecture based on electric field links between quantum computing modules demonstrating a connection rate of 2423 1/s with a success fidelity of transporting ions from one module to another of 99.999993%. While previous experiments were limited to a two qubit-gate fidelity of 98.5% because of the magnetic field gradient of only 24 T/m, our chip can produce up to 150 T/m, enabling entangling gates with fidelity above the relevant fault-tolerant threshold. As part of this project, you will carry out a demonstration of entanglement swapping between two quantum computing modules. This demonstration will include the realization of high-fidelity two-qubit gates on a chip, ion transport, including the demonstration of diabatic ion transport between the two quantum computing modules along with a full characterization of entanglement following the full swapping protocol. You will carry out a universal set of quantum computing operations in order to qualify the prototype device as a fully programmable multi-module quantum computer.
Eligibility
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.
This award is open to UK and International students.
