Research Studentship in Quantum Technologies

3.5-year D.Phil. studentship 

Project: Quantum interface engineering with solid-state spins and photons

Supervisors: Dr Dorian Gangloff

Engineered nanoscale systems that provide access to the quantum properties of matter are heralding a revolution in physics and technology. Control over single quantum objects, such as a single electron or photon, and over interactions between them provides the means to engineer the correlations that make quantum technologies a revolutionary advance over their current counterparts. Interfaces between material and optical quantum bits (qubits) will play a critical role in forming the inter-connects that will make quantum correlations useful.

Leading interfaces include solid-state light emitters, such as quantum dots. Fabrication within optical cavities places them as the brightest source of single photons of any physical system, while preserving state-of-the-art optical coherence properties. They are nanostructures where an electron qubit can be manipulated by laser pulses and serve as perfect systems to entangle photonic and spin degrees of freedom. This qubit further interacts with a nuclear register, and thus serves as a coherent proxy to exchange information between photons and nuclei. This combines the advantages of fast manipulation available in the optical domain, for processing, with the coherence of the nuclear domain, for memory. This capability is key to reaching scalable quantum networking tasks, such as realising a quantum repeater.

This project will investigate novel quantum dots that promise a major improvement in qubit coherence properties. The overall objective is to demonstrate that they can serve as a quantum networking node, which requires showing simultaneously: high-efficiency photon collection, qubit control, and a nuclear quantum memory. The project then aims to deliver benchmarking results on a multitude of quantum protocols forming the backbone of a quantum communication and computing network, such as deterministic photon-photon quantum gates, and distribution and storage of entanglement.

This project involves fundamental research in the field of quantum information science and engineering, including quantum optics, quantum control, materials science, and nanophotonics.

Eligibility

This studentship is funded through the UK Engineering and Physical Sciences Research Council (EPSRC) Doctoral Training Partnership and is open to Home students (full award – home fees plus stipend). Full details of the eligibility requirements can be found on the UK Research and Innovation website.

Award Value

Course fees are covered at the level set for Home students (c. £8620 p.a.). The stipend (tax-free maintenance grant) is c. £15,609 p.a. for the first year, and at least this amount for a further two and a half years.

Candidate Requirements

Prospective candidates will be judged according to how well they meet the following criteria:

  • A first class honours degree in Engineering, Physics or Materials Science
  • Excellent English written and spoken communication skills

The following skills are also highly desirable:

  • Knowledge of Quantum Mechanics (at the advanced undergraduate level)
  • Programming experience (i.e. Matlab, Python, etc.)
  • Strong laboratory-based skills

Application Procedure

Informal enquiries are encouraged and should be addressed to Dr Dorian Gangloff (dorian.gangloff@gmail.com)

Candidates must submit a graduate application form and are expected to meet the graduate admissions criteria.  Details are available on the course page of the University website.

Please quote 22ENGSQT_DG in all correspondence and in your graduate application.

Application deadline: noon on 3rd December 2021 (In line with the December admissions deadline, set by the University)

Start date: October 2022
