Accurate noise spectroscopy using quantum sensing ensembles
Dhilan T Vallury, Nikolai Dontschuk, Alexander M Jakob +2
Noise spectroscopy with quantum sensors is a powerful tool for characterising the properties of the sensor environment and detecting critical magnetic phenomena. While replacing si…
Persistence and emergence of quantum defects through pressure-induced phase changes
Alexander J Healey, Alan Salek, Christopher T-K Lew +15
Extreme pressures can transform materials and their properties, but probing these in-situ is made challenging by the small sample volumes and access requirements demanded by diamon…
A method for robust spin relaxometry in the presence of imperfect state preparation
Ella P. Walsh, Sepehr Ahmadi, Alexander J. Healey +2
Spin relaxometry based on quantum spin systems has developed as a valuable tool in medical and condensed matter systems, offering the advantage of operating without the need for ex…
Spin-dependent photoluminescence in carbon-based quantum dots
Erin S. Grant, Joseph F. Olorunyomi, Sam C. Scholten +12
The ability to modulate the photoluminescence (PL) of nanomaterials via spin-related effects is vital for many emerging quantum technologies, with nanoscale quantum sensing and ima…
The properties of the nitrogen-vacancy center in milled chemical vapor deposition nanodiamonds
Alessandro Mameli, Giannis Thalassinos, Marco Capelli +14
Fluorescent nanodiamonds (FNDs) containing negatively charged nitrogen-vacancy (NV-) centers are vital for many emerging quantum sensing applications from magnetometry to intracell…
Nitrogen-vacancy centre formation via local femto-second laser annealing of diamond
Davin Yue Ming Peng, Alexander J Healey, Rebecca Griffin +7
Emerging quantum technologies based on the nitrogen-vacancy (NV) centre in diamond require carefully engineered material with controlled defect density, optimised NV formation proc…
