Vacancies & Studentships
EPSRC DTP Studentships to support PhD / DPhil students on projects aligned with the NQIT research programme for entry in Sep/Oct 2019 will be coming soon… watch this space!
A fully funded 3.5 year PhD position is available in the Ion Trap Cavity-QED and Molecular Physics (ITCM) Group in the Department of Physics & Astronomy at the University of Sussex. The project is within the Networked Quantum Information Technologies (NQIT) Hub.
For more information, please contact Prof Matthias Keller (firstname.lastname@example.org).
This project unites two distinct areas of quantum information processing: single ions stored in radio-frequency traps and single photons in optical fibres. Both fields have seen spectacular advances in recent years. Strings of ions are presently the most successful implementation of quantum computing, with elementary quantum algorithms and quantum simulations realised. Photons are used to distribute entanglement over ever increasing distances.
The principal challenge in the field is to enhance quantum processing power by scaling up current devices to larger quantum systems. We are pursuing one of the most promising strategies, distributed quantum computation, in which multiple small-scale ion processors are interlinked by exchanging photonic quantum bits via optical fibres. This requires novel ion trap structures that facilitate high-performance quantum computation and a photonic interconnect for networking. To create a high efficiency ion-photon interconnect for networking, we use miniature optical cavities. The Ion Trap Cavity-QED and Molecular Physics group in Sussex has a leading role in this field.
The aim of this project is to design, build and test a compact ion based quantum information processor. It consists of a linear ion trap with several separate trapping regions in which the ions can be loaded, cooled and quantum information processing can be performed. In addition, the structure contains a trapping region in which an optical micro-cavity is employed as a quantum interconnect between different quantum processors. The project involves the simulation of the ion trapping structure and the ion dynamic in the ion trap as well as the shuttling between different trapping regions. The optimised trapping structure will then be fabricated using micro-fabrication techniques and characterised. The transfer of ions between the various trapping regions and the quantum interconnect will be tested.
Skills and training
An important part of this PhD project is the skills development and training. Local training through lecture courses, transferable skills training modules and practical training in the laboratory will be complemented by SEPNet wide training events. These include workshops and training schools.
£14,777 per annum tax-free bursary and waiver of UK/EU fees each year for 3.5 years, as well as funding for research training and travel. Additional funding may also be available to support placements with outside partners for a further period of six months in total.
Applicants should hold, or expect to hold, a UK undergraduate degree in physics or engineering. If you are unsure about the equivalence of your qualifications, please contact us at email@example.com
Due to funding restrictions, the studentship is open to UK and EU resident students only. However, we also welcome applications from self-funded non-EU students

The Research Group, Optical Engineering and Quantum Photonics, in the Optoelectronics Research Centre at the University of Southampton, specialises in the development and manufacturing of novel optoelectronic devices for applications in quantum technology, integrated optical sensors and laser optics.
Ultra-precision machining for ion trap quantum computing
We have a studentship available to investigate the manufacture of ion traps for quantum computing. The studentship is supported by the UK’s Quantum Technologies programme and is associated with the national quantum computing hub (NQIT) led by the University of Oxford. This work will address the key engineering challenge in realising ion based quantum computing. The project will explore and develop techniques to assemble Ion trap optical assemblies with ultra-high positional tolerance in a miniaturised format. The project will use new techniques, i.e. ultra-precision machining, to diamond machine features with 25nm resolution and incorporates cleanroom processes, to integrate microwave electronics and optics to manipulate ions. These new devices will enable scaling of ion based quantum computing to produce state-of-the-art robust quantum computation.
We are looking for someone with a background/interest in engineering as a great deal of the PhD will be fabrication and laboratory based. An understanding of photonics or quantum engineering is desirable, but not essential. The candidate will work with the recently commissioned £1.3m dedicated suite of ultra-precision tools within the research group.
The PhD programme
Our world-leading research centre is a hive of activity with over 200 staff and students working on cutting-edge research to provide innovative solutions for real life problems in manufacturing, communication technology, defence, health care, renewable energy and the environment.
We are looking for the photonics pioneers of the future to join our vibrant research team and work alongside our world-class researchers to make history. Our physics and materials science PhD programme offers a solid start to any career in optics and photonics, whether you are planning to stay in academia or work in industry.
Applications would be welcome from candidates holding good degrees (1st class, 2:1 honours or MSc) in physics, materials science, mechanical or electronic engineering. Experimental skills are essential. In addition to the standard EPSRC PhD studentship, this position includes an annual allowance to enable attendance at international conferences. This post is open to UK and EU citizens only, due to standard EPSRC eligibility requirements. https://www.orc.soton.ac.uk/fees-and-funding

The Optoelectronics Research Centre at the University of Southampton is looking for a candidate with an interest in quantum technology and a strong background in theory and computational simulation in classical and/or quantum optics to join us on this interdisciplinary project as part of the Networked Quantum Information Technologies (NQIT) programme.
One of the leading contenders for quantum information technology is based on cold trapped ions interacting via single photons. However, in current state-of-the-art experiments the coupling between ions and photons is still very inefficient and is mainly achieved through conventional lenses and mirrors.
The main goal of this project is to investigate how this optical access can be provided by optical waveguides integrated on the same chip that holds the ion trap. We will investigate different types of waveguides and ion-photon coupling via gratings, tapers, Fresnel lenses and other mode converters. Integration of Bragg reflectors and dielectric coatings to form resonators will be considered. Light polarisation must be considered carefully and coupling coefficients to specific ion transitions and collection efficiencies of emitted photons will be simulated and optimised to support the development of fully integrated chips for future quantum applications.
We offer an enhanced stipend of £18k per year for UK students.
