The Optoelectronics Research Centre at the University of Southampton invites applications for a fixed-term 2-year postdoctoral position in the area of theory and simulation of integrated photonics for chip-based quantum computing applications.
This post is part of the new EPSRC Hub in Quantum Computing and Simulation, a nationwide network of universities and industrial partners to develop the next generation of quantum technology devices, led by the University of Oxford. You will join a vibrant and friendly interdisciplinary team of theorists, fabricators, and experimentalists in Southampton and collaborate with our partners across the Hub.
Cold trapped ions interacting via single photons have emerged as a leading platform for quantum information processing and quantum computing. The goal of this project is to miniaturise this technology on planar chips. In particular, you will be working on the design and simulation of the integration of optical components, such as waveguides, couplers, beamsplitters, mode converters, and resonators. Such optical integration will then allow for on-chip laser cooling of the atomic motion as well as optical quantum state preparation, manipulation, and read-out. The optimised devices will be fabricated in the Southampton cleanrooms and will then be incorporated in the experiments in Oxford.
You will need a PhD in Physics, Engineering, or a related discipline and a detailed understanding of optics and photonics. You should have previous experience in numerical methods and computer simulation, ideally with knowledge of finite element simulations (e.g. in Comsol) and/or other computational photonics tools and programming languages.

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.

University of Warwick is looking for a post-graduate student to join the quantum information science group of Animesh Datta. The goals of this theoretical project are to produce the design principles for quantum sensors that can tackle some of the most fundamental open problems in physics. Instances include the direct detection of dark matter, testing the validity of quantum mechanics in macroscopic systems, searching for time variation of fundamental constants, and the direct detection of gravitational waves from exotic sources. The principle underlying all of these questsis the precise sensing of physical observables such as exquisitely small forces, phases, displacements and temperature.
The student must be interested in a close interplay of quantum metrology, quantum information science, quantum optics, and quantum mechanics.
The laws of quantum mechanics set the fundamental limit of precision sensing. Quantum metrology is the study and application of these fundamental limits. Quantum metrology, using ideas from quantum information science, is ushering in a new era of precision sensing. This spans the sensing of time, position, force, magnetic and electric fields, temperature and many other physical parameters with unprecedented precision.
This PhD project shall leverage the concepts and development underlying these recent advances such as multi-parameter  and multi-mode  quantum metrology to invent new routes for attacking open problems in fundamental physics. It will apply quantum metrology to physical systems such as atomic, optical, and opto-mechanical interferometers, and their performance in the real world. Each one of these systems possesses features that make them ideal for specific open problems. For instance, opto-mechanical systems with massive objects in quantum superpositions are ideal for testing the validity of quantum mechanics in macroscopic systems.
An aim of the project is to advance recent results from Warwick  towards experimental systems that can be realized in the coming years. The outcomes of this project will also have applications in designing the next generation of quantum-enhanced imaging, magnetometry, and time keeping.
A close interaction between theory and experimental systems will place the student in a uniquely beneficial position for a future in fundamental physics and the quantum technologies market. The interaction with premier scientific missions will provide the student a privileged perspective on quantum sensing and metrology in a complementary setting, unavailable to any other in the UK or elsewhere.

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.

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 (email@example.com).
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 firstname.lastname@example.org
