PhD in Quantum Communication Networks and Solid-State Entangled Photon Sources University College London in United Kingdom

This PhD opportunity is offered as part of University College London's Quantum Doctoral Programme, in collaboration with Toshiba Europe Ltd and the Quantum Information Group. The project focuses on the optimization of solid-state entangled photon sources for quantum communication networks, aiming to advance quantum information processing and quantum networking. Research will address key challenges in the generation and distribution of entanglement, including fine-structure splitting, charge noise, dephasing, and efficient coupling of quantum dot emission into optical fibres or integrated photonic devices.

The project leverages nanophotonic engineering and advanced optical excitation schemes to develop scalable entangled photon sources suitable for quantum networking applications. Students will gain hands-on experience in quantum optics, semiconductor nanofabrication, and photonic device integration, working within a highly collaborative environment at Toshiba Europe Limited in Cambridge. The role offers opportunities to engage with both academic and industrial partners, providing a unique perspective at the intersection of quantum optics, nanofabrication, and quantum communication.

Applicants should have or expect to obtain a first-class or upper second-class degree in Physics, Electronic Engineering, or a related discipline. Preferred backgrounds include optics, semiconductor physics, or quantum physics, with familiarity in programming languages such as MATLAB or Python for data analysis. The project is experimental and requires on-site laboratory work, as well as strong teamwork and communication skills.

The position is co-supervised and co-sponsored by industry, providing exposure to both academic and industrial research environments. The application deadline is 3 February 2026.
