About the project
Spin-based quantum sensing converts tiny quantum signals into detectable responses by aligning microscopic spins, for example in diamond nitrogen-vacancy centres. Can this alignment be exploited to amplify responses in other systems? This project addresses that question—theoretically and experimentally—via novel transfer protocols utilising periodic control fields and Floquet-engineering methods.
Optically active colour centres, such as diamond nitrogen-vacancy (NV) centres, have emerged as promising quantum devices for quantum computation and quantum sensing applications, as well as efficient sources of spin hyperpolarization. While control via external fields is common to many quantum platforms, NV diamonds are uniquely flexible in that their operational mode can be dynamically reconfigured through optical and magnetic control, or any combination of these.
In this project, you will develop novel nuclear hyperpolarization protocols (Dynamic Nuclear Polarization, DNP) exploiting the capabilities of NV diamond centres as versatile polarization injectors, with practical applications in spin-based quantum sensing. Unlike typical DNP techniques that require strong external magnetic fields, optical spin injection with NV centres operates effectively without them. Moreover, the periodic control fields (Floquet protocols) used for DNP can be readily adapted to facilitate quantum sensing operations.
The project will encompass engineering, experimental, and theoretical components, tailored to the candidate’s interests. You will gain valuable experience and expertise in optical and radio-frequency quantum control strategies, such as Floquet-engineering and Dynamic Decoupling, common to a large variety quantum technologies.
