This final chapter summarizes some of the emerging topics in the usage of diamond for quantum information processing. Practical applications include biosensing and bioimaging using colour centres in diamond, as well as pathways towards integrated quantum photonics using diamond as a platform. On the other hand, challenges will be discussed, including surface terminations and engineering new, superior optically active defects. Finally, we discuss the outlook for the field of quantum information processing (QIP) with diamond.
