摘要: We study the coupling of a single nitrogen-vacancy center in diamond to nearby nitrogen defect at room temperature. The magnetic dipolar leads splitting electron spin resonance frequency center, allowing readout state spin. At fields where two centers is same, we observe strong polarization amount can be controlled by optical excitation power. combine and time-resolved pump-probe measurements determine relaxation time Finally, discuss indications for hyperfine-induced nuclear
