Nitrogen-Vacancy Centers as Nuclear Polarization Injectors for Spin-Based Quantum Sensing

This PhD project, based at the University of Southampton within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, explores the use of diamond nitrogen-vacancy (NV) centers as nuclear polarization injectors for spin-based quantum sensing. The research aims to develop novel nuclear hyperpolarization protocols, specifically Dynamic Nuclear Polarization (DNP), leveraging the unique capabilities of NV centers to inject polarization without the need for strong external magnetic fields. The project combines theoretical and experimental approaches, utilizing periodic control fields and Floquet-engineering methods to amplify quantum signals and facilitate quantum sensing operations. NV centers are optically active color centers in diamond, recognized for their flexibility in quantum computation and sensing applications. Their operational modes can be dynamically reconfigured using optical and magnetic control, making them versatile tools for quantum technologies. The successful candidate will gain expertise in optical and radio-frequency quantum control strategies, including Floquet-engineering and Dynamic Decoupling, which are widely applicable across quantum platforms. The project is tailored to the candidate’s interests and may encompass engineering, experimental, and theoretical components. Applicants from various scientific backgrounds are encouraged, with preference given to those possessing strong mathematical skills, experience in optics or magnetic resonance, and a background in quantum physics. The position offers substantial training in scientific, technical, and commercial skills, and is supported by a competitive UKRI TechExpert stipend of approximately £31k per year for UK students, with funding also available for EU, Horizon Europe, and international students. The University of Southampton is committed to equality, diversity, and inclusivity, and welcomes applications from candidates seeking part-time study. The institution provides support for personal circumstances and has onsite childcare facilities. The application deadline is July 31, 2026, with an earlier deadline for international applicants. For further information, candidates are encouraged to contact Dr Christian Bengs or Prof Malcolm Levitt.
