The so-called nitrogen vacancy (NV) centre in nanodiamond could be ideal for use in future quantum technologies, including quantum computing and nanoscale sensing. However, many applications would benefit from integrating the NVs with high-quality optical cavities that can couple to and enhance the amount of light emitted from these structures. One major challenge here is to be able to precisely position the NV within such cavities and on the nanoscale, something that has been difficult for researchers to do so far. A new technique developed by a team in the US and Australia that makes use of “delta doped” NV centres may help in overcoming this problem……
