    "abstract": "We study the coupling of a single nitrogen-vacancy center in diamond to a\nnearby single nitrogen defect at room temperature. The magnetic dipolar\ncoupling leads to a splitting in the electron spin resonance frequency of the\nnitrogen-vacancy center, allowing readout of the state of a single nitrogen\nelectron spin. At magnetic fields where the spin splitting of the two centers\nis the same we observe a strong polarization of the nitrogen electron spin. The\namount of polarization can be controlled by the optical excitation power. We\ncombine the polarization and the readout in time-resolved pump-probe\nmeasurements to determine the spin relaxation time of a single nitrogen\nelectron spin. Finally, we discuss indications for hyperfine-induced\npolarization of the nitrogen nuclear spin.",
