Surface adsorbates suppress low-frequency noise for shallow nitrogen-vacancy centers
Zhiyang Yuan, David A. Fehr, Kalliope Zervas +5
Shallow nitrogen-vacancy (NV) centers in diamond are promising nanoscale quantum sensors, yet their coherence is strongly limited by surface-induced noise. Surface adsorbates are w…

High-Efficiency, High-Fidelity Charge Initialization of Shallow Nitrogen Vacancy Centers in Diamond
Marjana Mahdia, Artur Lozovoi, Jared Rovny +3
Nitrogen vacancy (NV) centers in diamond exhibit long spin coherence times, optical initialization, and optical spin readout under ambient conditions, making them excellent quantum…
