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…
Photoluminescence decomposition analysis: a technique to characterize NV creation in diamond
Scott Alsid, John Barry, Linh Pham +4
Treatment of lab-grown diamond by electron irradiation and annealing has enabled quantum sensors based on negatively-charged nitrogen-vacancy (NV) centers to demonstrate…
Decoherence of dipolar spin ensembles in diamond
Erik Bauch, Swati Singh, Junghyun Lee +8
We present a combined theoretical and experimental study of solid-state spin decoherence in an electronic spin bath, focusing specifically on ensembles of nitrogen vacancy (NV) col…
Sensitivity Optimization for NV-Diamond Magnetometry
John F. Barry, Jennifer M. Schloss, Erik Bauch +4
Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an increasingly favored quantum sensing platform. However, present NV ensemble devices exhibi…
Hamiltonian Engineering with Constrained Optimization for Quantum Sensing and Control
Michael F. O'Keeffe, Lior Horesh, John F. Barry +2
While quantum devices rely on interactions between constituent subsystems and with their environment to operate, native interactions alone often fail to deliver targeted performanc…
