PhD Studentship: Threading quantum states of light through complex scattering media PhD (fully funded)

Fully-funded PhD Studentship – Threading quantum states of light through complex scattering media

We are offering a fully-funded PhD studentship in the field of quantum photonics (UK/international tuition fees covered). The aim of project is to develop a new experimental platform to control quantum states of light as they propagate through complex scattering media, with future applications to quantum networking, computing and sensing.

Quantum technologies exploit the unique properties of quantum physics to deliver functionality that cannot be achieved using classical physics alone. A key challenge is the fragility of quantum states that are very easily disrupted by uncontrolled interactions with their environment. A front-running strategy to shuttle quantum information around is by encoding it into single photons. An emerging area is the encoding of quantum information into the spatial states of photons.

Using wavefront shaping technologies it is possible to manipulate high-dimensional entangled states in the spatial modes of light [1]. In this project we will build upon our research group’s expertise in controlling classical light states through scattering media [2-4], extending these approaches to enable quantum states of light to be guided through dynamically changing complex scattering media. Among the possible applications are the development of quantum communication protocols over free-space optical links, compensating for scattering of entangled photons in media such as multimode fibres and the turbulent atmosphere, and the realisation of logic gates to perform quantum computation operations.

This is a 3.5-year PhD position based in the Structured Light Lab, within the Department of Physics and Astronomy at the University of Exeter (Streatham campus, Exeter). The Structured Light Lab is led by Prof. David Phillips and consists of a dynamic team of PhD and postdoctoral researchers working at the forefront of photonics research. You will conduct your research in the Lab’s dedicated state-of-the-art laser laboratory facilities, which are well-supported by active grants from the European Research Council, and the UK Engineering and Physical Science Research Council. You will gain expertise in experimental optics and quantum photonics, and specific skills in programming (e.g., python). The project will be co-supervised by Prof. Simon Horsley (an expert in quantum theory) and Dr Callum Jones (with experience in developing quantum optics platforms). The PhD studentship includes travel resources for research visits and attendance at the leading international conferences in the field.

The ideal candidate should have an enthusiasm for experimental physics and programming. This project will suit a candidate with a background in one of the following disciplines: Physics, Optics, Electronic Engineering, Computer Science, Natural Sciences, Quantum technologies, although we are open to any enthusiastic applicant with a science-related background.

The start date of the studentship is October 2026 (or earlier or soon thereafter). The award covers UK/International tuition fees plus an annual tax-free stipend for a duration of 3.5 years (full time) or part time equivalent. The stipend will be at least £20,780 per yr. (current 2025-26 rate). The studentship will be awarded on the basis of merit.
