For the past decades, color centers in diamond have evolved into possible key ingredients for quantum photonic applications such as quantum light sources or quantum memories [1] because of their promising optical characteristics. Quantum light sources as a building-block for photonic integrated circuits can be realized by embedding a single diamond color center into a diamond cavity [2]. The reliable fabrication of such photonic stuctures requires the localization of single color centers in bulk diamond with an accuracy of down to tens of nanometers [3].
We present our progress in improving the localization accuracy towards the required level. This will enable the high-yield deterministic fabrication of diamond-based quantum emitters.
