Rapid, in-situ neutralization of nitrogen- and silicon-vacancy centers in diamond using above-band-gap optical excitation
Christian Pederson, Nicholas S. Yama, Lane Beale +2
The charge state of a quantum point defect in a solid state host strongly determines its optical and spin characteristics. Consequently, techniques for controlling the charge state…
Impact of surface and laser-induced noise on the spectral stability of implanted nitrogen-vacancy centers in diamond
Srivatsa Chakravarthi, Christian Pederson, Zeeshawn Kazi +2
Scalable realizations of quantum network technologies utilizing the nitrogen vacancy center in diamond require creation of optically coherent NV centers in close proximity to a sur…
Inverse-designed photon extractors for optically addressable defect qubits
Srivatsa Chakravarthi, Pengning Chao, Christian Pederson +6
Solid-state defect qubit systems with spin-photon interfaces show great promise for quantum information and metrology applications. Photon collection efficiency, however, presents…
A window into NV center kinetics via repeated annealing and spatial tracking of thousands of individual NV centers
Srivatsa Chakravarthi, Chris Moore, April Opsvig +6
Knowledge of the nitrogen-vacancy center formation kinetics in diamond is critical to engineering sensors and quantum information devices based on this defect. Here we utilize the…
