Vector magnetometry using cavity-enhanced microwave readout in nitrogen-vacancy diamond
Reginald Wilcox, David Phillips, Matthew Steinecker +6
We demonstrate -steradian vector magnetic field sensing using an ensemble of nitrogen-vacancy (NV) centers in a single-crystal diamond coupled to a microwave (MW) cavity. The M…

Thermally-Polarized Solid-State Spin Sensor
Reginald Wilcox, Erik Eisenach, John Barry +4
Quantum sensors based on spin defect ensembles have seen rapid development in recent years, with a wide array of target applications. Historically, these sensors have used optical…

Cavity quantum electrodynamic readout of a solid-state spin sensor
Erik R. Eisenach, John F. Barry, Michael F. O'Keeffe +4
Robust, high-fidelity readout is central to quantum device performance. Overcoming poor readout is an increasingly urgent challenge for devices based on solid-state spin defects, p…
