Visible Emitters in Hexagonal Boron Nitride as an Optically Addressable Spin Qubit Platform
… using optically detected magnetic resonance (ODMR) techniques. The first manifold corresponds to a spin signature with small zero-field splitting (D/h < 30 MHz). Interestingly, the sign of ODMR contrast for this resonance can be positive or negative, likely arising from variability in the …

Interfacing spin-based quantum sensors with complex systems
… sensitivity. This forms the basis of optimal ODMR frequency sampling in situations where the ODMR lineshape fluctuates. It was also demonstrated that it is possible to simultaneously perform ODMR measurements and track single nanodiamonds, using an orbital tracking method. This enables a …

NV diamond project for nEDM
… first, Optically Detected Magnetic Resonance (ODMR) allows us to probe the Zeeman and Stark induced shifts in the ground state through resonant microwave spectroscopy. This technique has helped us study and characterize the response of the NV center to electromagnetic fields. The use of the NV …

Wide-field magnetic field imaging with nitrogen vacancy centers in nanodiamonds at high frame-rates
… and optically detected magnetic resonances (ODMR). The NV has been shown to be a sensitive magnetometer at room temperature. In particular, owing to their small size, NV centers in nanocrystals (nanodiamonds) offer magnetic field imaging with high spatial resolution. Competitive magnetic …

Nanoscale magnetometry with a microcontroller-based magnetometer using a single nitrogen-vacancy defect in nanodiamond
… state by Optically Detected Magnetic Resonance (ODMR). In the present work, an ODMR−based system for performing nanomagnetometry was developed using an Arduino Due board microcontroller as a main tool for the magnetometer implementation by means of an established in-system programming. The …

Optics-Based Quantum Information and Sensing Platforms Utilizing the Nitrogen-Vacancy Center in Diamond
… allow for optically detected magnetic resonance (ODMR), with the resonant frequency depending on the local magnetic field. Two-dimensional images of the magnetic field at the surface of the diamond are thus obtained, with a magnetic field sensitivity of 2.4 μT. The microscope was able to detect …

Development of a Compact Diamond NV- Magnetometer
… obtaining optically detected magnetic resonance (ODMR) signals for NV− centres under controlled magnetic fields. Key system components such as a stabilized laser excitation source, diamond NV− sample, and optical path components have been integrated into a modular design, allowing room for …

Opportunities for multimodal quantum sensing in intracellular environments
… using optically detected magnetic resonance (ODMR) and combined with the subdiffraction resolution single- particle tracking a sensitivity of 2.3 K/√Hz and 3.7 nm spatial resolution was achieved. This dual-modal sensor is used to study the temperature dependence of viscosity and …
