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

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.

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.
