The interaction between photons and single quantum systems is a key question and necessity for quantum information processing in means of reading, writing, and storing information. In our study we investigate the efficient optical interaction between a laser beam and a negative charged nitrogen-vacancy (NV−) center in diamond – a promising solid state spin qubit. We are able to observe the interference and the relative phase shift between the exciting laser and the coherently emitted photons. This allows us to distinguish the coherently and the incoherently scattered photons within the narrow zero phonon line.
