Stark Tuning and Electrical Charge State Control of Single Divacancies in Silicon Carbide
Charles F. de las Casas, David J. Christle, Jawad Ul Hassan +3
Neutrally charged divacancies in silicon carbide (SiC) are paramagnetic color centers whose long coherence times and near-telecom operating wavelengths make them promising for scal…
Isolated spin qubits in SiC with a high-fidelity infrared spin-to-photon interface
David J. Christle, Paul V. Klimov, Charles F. de las Casas +11
The divacancies in SiC are a family of paramagnetic defects that show promise for quantum communication technologies due to their long-lived electron spin coherence and their optic…
High fidelity bi-directional nuclear qubit initialization in SiC
Viktor Ivády, Paul V. Klimov, Kevin C. Miao +6
Dynamic nuclear polarization (DNP) is an attractive method for initializing nuclear spins that are strongly coupled to optically active electron spins because it functions at room…
Theoretical model of the dynamic spin polarization of nuclei coupled to paramagnetic point defects in diamond and silicon carbide
Viktor Ivády, Krisztián Szász, Abram L. Falk +6
Dynamic nuclear spin polarization (DNP) mediated by paramagnetic point defects in semiconductors is a key resource for both initializing nuclear quantum memories and producing nucl…
Optical polarization of nuclear spins in silicon carbide
Abram L. Falk, Paul V. Klimov, Viktor Ivády +5
We demonstrate optically pumped dynamic nuclear polarization of 29-Si nuclear spins that are strongly coupled to paramagnetic color centers in 4H- and 6H-SiC. The 99 +/- 1% degree…
Isolated electron spins in silicon carbide with millisecond-coherence times
David J. Christle, Abram L. Falk, Paolo Andrich +6
The elimination of defects from SiC has facilitated its move to the forefront of the optoelectronics and power-electronics industries. Nonetheless, because the electronic states of…
All-optical control of a solid-state spin using coherent dark states
Christopher G. Yale, Bob B. Buckley, David J. Christle +4
The study of individual quantum systems in solids, for use as quantum bits (qubits) and probes of decoherence, requires protocols for their initialization, unitary manipulation, an…
Fluorescence thermometry enhanced by the quantum coherence of single spins in diamond
David M. Toyli, Charles F. de las Casas, David J. Christle +2
We demonstrate fluorescence thermometry techniques with sensitivities approaching 10 mK Hz^(-1/2) based on the spin-dependent photoluminescence of nitrogen vacancy (NV) centers in…
Electron spin resonance of nitrogen-vacancy centers in optically trapped nanodiamonds
Viva R. Horowitz, Benjamín J. Alemán, David J. Christle +2
Using an optical tweezers apparatus, we demonstrate three-dimensional control of nanodiamonds in solution with simultaneous readout of ground-state electron-spin resonance (ESR) tr…
Measurement and Control of Single Nitrogen-Vacancy Center Spins above 600 K
D. M. Toyli, D. J. Christle, A. Alkauskas +3
We study the spin and orbital dynamics of single nitrogen-vacancy (NV) centers in diamond between room temperature and 700 K. We find that the ability to optically address and cohe…
