Photon interference among distant quantum emitters is a promising method togenerate large scale quantum networks. Interference is best achieved whenphotons show long coherence times. For the nitrogen-vacancy defect center indiamond we measure the coherence times of photons via optically induced Rabioscillations. Experiments reveal a close to Fourier transform (i.e. lifetime)limited width of photons emitted even when averaged over minutes. The projectedcontrast of two-photon interference (0.8) is high enough to envisage theapplications in quantum information processing. We report 12 and 7.8 ns excitedstate lifetime depending on the spin state of the defect.
