Title: Master equation-based model for infrared-based magnetometry with nitrogen-vacancy centers in diamond cavities: a path to sub-picotesla sensitivity at sub-millimeter scales

Abstract summary: We develop a master-equation treatment of optically detected magnetic resonance, incorporating IR light saturation effects. We show that our model is compatible with experiments of IR-based NV center magnetometry. We uncover the potential to achieve sensitivities in the order of sub-pico tesla, even for sub-millimeter scales.

Abstract: Our study aims to increase the spatial resolution of high-sensitivity magnetometry based on singlet-transition infrared (IR) absorption using nitrogen-vacancy (NV) centers in diamonds in monolithic cavities, with potential applications in bio-magnetic field detection. We develop a master-equation treatment of optically detected magnetic resonance, incorporating IR light saturation effects. This master equation provides the singlet population, which is then utilized to calculate the reflectivity and ultimately derive the magnetic field sensitivity taking into account photon and spin shot noise. We further show that our model is compatible with experiments of IR-based NV center magnetometry. Through optimization in a high-parameter space, we uncover the potential to achieve sensitivities in the order of sub-pico tesla, even for sub-millimeter scales.

Towards high-sensitivity magnetometry with nitrogen vacancy centers in diamond using the singlet infrared absorption [0.0]
We report on the optimization efforts of the magnetometer sensitivity at room temperature and without cavities. We reach sensitivities of 18 pT$/sqrtmathrmHz$, surpassing previously reported values. We also report on a defect that is native to CVD-grown diamond and thus absent in HPHT diamond, the excitation of which impacts the measured singlet absorption signal.

All-Optical Nuclear Quantum Sensing using Nitrogen-Vacancy Centers in Diamond [52.77024349608834]
Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors. We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing. Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.

Measuring the magnon-photon coupling in shaped ferromagnets: tuning of the resonance frequency [50.591267188664666]
cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures. Speed enhancement is usually achieved by optimizing the geometry of the electromagnetic cavity. We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

Solid state defects in diamond make promising quantum sensors with high sensitivity andtemporal resolution. Inhomogeneous broadening and drive amplitude variations have differing impacts on the sensitivity depending on the sensing scheme used. We numerically investigate and compare the predicted sensitivity of schemes based on continuous-wave (CW) optically detected magnetic resonance (ODMR) spectroscopy, pi-pulse ODMR and Ramsey interferometry.
